Woodmorappe's Collection of Bad Dates

How Good Are Those Young-Earth Arguments?
A Close Look at Dr. Hovind's List of Young-Earth Arguments and Other Claims
by Dave E. Matson

We will now look at several arguments, which may or may not be supported by Dr. Hovind, that enjoy a wide circulation. I will also present a couple of arguments indicating that the earth is much older than a few thousand years.


A1. Woodmorappe's Collection of Bad Dates


Eat one of those and your tummy will curl right up! Seriously speaking, a favorite attack on radiometric dating involves dangling "horror stories" about gross errors before the reader, thus giving the impression that radiometric dating is totally unreliable. Woodmorappe (1979), with his collection of some 350 bad radiometric dates, must surely be the master of that technique.


Upon being presented with claims that radiometric dating is totally erroneous, a question naturally arises:


If radiometric geochronology is half as bad as Woodmorappe's list suggests, then how in the world did geologists ever arrive at a tight consensus for the official dates? Look at the various radiometric tables in use over the last 20 years or so and you will find, at least for the fossil-bearing strata, a remarkably tight agreement. ... Did the geochronologists throw darts to determine the accepted dates?


(Matson, 1993, p.1)


Either we have a worldwide conspiracy among geologists, which no sane person believes, or else the numerous radiometric dates were consistent enough to allow that kind of close agreement. In fact, Dr. Dalrymple, an expert in radiometric dating with lots of hands-on experience, puts the percentage of bad dates at only 5-10 percent.


Thus, we clear away the first illusion spun by creationism, namely that most of the dates are bad, that the radiometric picture is totally chaotic. In fact, it is not at all unusual for several different radiometric methods to agree within a few percentage points on a date. When you consider that each radiometric method is subject to different types of error, that the different "clocks" run at different speeds, such an agreement would be extremely rare on the basis of pure chance. In a number of instances, more than you might imagine, dates are further corroborated by methods that have nothing to do with radioactivity. Thus, the big, statistical picture painted by radiometric dating is excellent. Today, we have some 100,000 radiometric dates, the vast majority contributing sensibly to the overall picture.


Woodmorappe's main theme, minus the diplomatic wording, is that geologists are cheating like so many schoolboys to make their dates come out right. But even schoolboys need to know what the right answers are in order to cheat, and there was no absolute age list when radiometric dating was first applied to the strata.


Anyone can make up a list of bad cars, bad people, bad neighborhoods, or bad radiometric dates. What does that prove? Is it unsafe for you to drive a car, to meet new people, or to live in a neighborhood? Of course not!


The thing that is lacking in Woodmorappe's argument is statistical balance. He is very good at showing the many ways that things can go wrong; he has not shown that things normally go wrong.


To be sure, Woodmorappe isn't claiming that his table is a normal sample of radiometric dates. His is a table of discordant dates. However, in order to make his case against radiometric dating he must, at the very least, show a high percentage of bad dates among the credible radiometric candidates. This cannot be done by merely citing the numerous ways in which one can get a bad date; nor is it achieved by concentrating on atypical cases. Such information is certainly interesting, a healthy reminder of what can go wrong, but it is no threat to the radiometric dating methods which, after all, measure their successes on a statistical basis.


(Matson, 1993, p.2)


Thus, Woodmorappe is acting more like a mechanic who informs a car owner of the many ways that her car can break down, who quotes numerous horror stories to illustrate his points. Even if those horror stories were true, the mechanic has failed to prove that the lady's car needs repair, let alone junking.


How different it would be if the mechanic pulled out a statistical study done by a consumer magazine to show that the particular make and year for the lady's car was unreliable, due to certain parts, after so many miles. That kind of balanced statistical study is the very thing Woodmorappe's paper lacks.


An eye-opener awaits anyone who closely examines Woodmorappe's list of bad dates. Some of the dates involved minerals that even Woodmorappe admits are unreliable. No geologist would normally use such minerals.


Some of the dates are experimental! Since when do we count experimental work? The idea of experimental dating is to see whether a given radiometric method can be applied to certain materials or under certain conditions. The results make the method stronger, either by advising us to avoid certain minerals under certain conditions or by building our confidence in applying it to new materials or situations.


A great many dates, perhaps most, are rejects. That is, they were rejected because of internal indicators (such as a bad isochron) rather than on the basis of the final date produced. If the radiometric method is to be indicted, it must be indicted by dates which were counted as good but shown, by other means, to be bad. Rejects don't fall into that category. They can't be used against the radiometric method.


All of the dates lack the investigator's personal, detailed interpretation. That's no way to make a case for a bad date! Again, one must demonstrate that a bad date would have been counted as a good date had it not been contradicted by outside data. Properly interpreted, a number of gross "errors" listed in Woodmorappe's table simply vanish! A spectacular example showcased by Woodmorappe, though not actually listed in his table, deals with an example from California.


The Pharump diabase from the Precambrian of California yielded an Rb-Sr isochron of no less than 34 b.y., which is not only 7 times the age of the earth but also greater than some uniformitarian estimates of the age of the universe. This super-anomaly was explained away by claiming some strange metamorphic effect on the Sr.


(Woodmorappe, 1979, p.122)


Sounds pretty grim, huh? The unsuspecting reader would assume that here is a real disaster which geochronologists were trying to cover up with some phoney explanation! In fact, the 34-billion-year figure is the result of an incompetent reading of the data, an attempt by Woodmorappe to see an isochron where none exists!


The data do not fall on any straight line and do not, therefore, form an isochron. The original data are from a report by Wasserburg and others [1964], who plotted the data as shown but did not draw a 34-billion-year isochron on the diagram. The "isochrons" lines were drawn by Faure and Powell [1972] as "reference isochrons" solely for the purpose of showing the magnitude of the scatter in the data. ... The scatter of the data in Figure 6 shows clearly that the sample has been an open system to (strontium-87) Sr-87 (and perhaps to other isotopes as well) and that no meaningful (rubidium-strontium) Rb-Sr age can be calculated from these data. This conclusion was clearly stated by both Wasserburg and others [1964] and by Faure and Powell [1972]. The interpretation that the data represent a 34-billion-year isochron is solely Woodmorappe's [1979] and is patently wrong.


(Dalrymple, 1984, pp.78-79)


Whatever the reasons may be for the scatter, the fact remains that these data were clearly a "discard" case. Thus, this example cannot be used against the Rb-Sr method. That Woodmorappe would see an isochron where none could possibly exist, by misinterpreting one of the lines Faure and Powell had drawn, this in spite of the fact that those authors stated that the data cannot be used, strongly suggests that Woodmorappe's search for discordant dates is superficial. One wonders how many other obvious discards are hiding in his table.


(Matson, 1993, p.7)


Perhaps, by now, you can understand why long lists of bad dates do not, in themselves, impress scientists. The success of such an attack on radiometric dating hangs on a detailed, case by case analysis as well as a clear demonstration that the sample is representative of the whole to some meaningful degree. In my paper (1993) I listed about 10 conditions which must be examined in any meaningful study of bad dates.

Dating Methods

How Good Are Those Young-Earth Arguments?
A Close Look at Dr. Hovind's List of Young-Earth Arguments and Other Claims

Dr. Hovind: The assumed age of a sample will dictate which radiometric dating method is used. One method will only give results for a young age; another will only give results for a very old age. Thus, the assumed age of a sample dictates the method which, in turn, gives the assumed age!

. That seems to be Dr. Hovind's complaint, one that has been made by other creationists. Are we to believe that the world's leading geologists cannot recognize an elementary case of circular reasoning? Is that the real explanation behind their choice of isotopes in radiometric dating? Of course not! Those creationists arguing thus have been grievously blinded by their religious prejudice, against which even a Ph.D. is no defense.


The problem lies with Dr. Hovind and many other creationists who haven't the foggiest idea how radiometric dating works! They are the last people who should be criticizing it. The explanation is so easy that quotations from specialists won't even be necessary.


If you test an old sample with a radiometric method geared to young samples, you would find that all the "parent" radioactive atoms have decayed. Your conclusion would be that the sample has a minimum age which corresponds to the smallest amount of the "parent" nuclide you can detect. You would not conclude that the sample was "young."


If you test a young sample with a radiometric method geared to old samples, you would find that none of the "parent" radioactive atoms have decayed. Your conclusion would be that the sample has a maximum age which corresponds to the smallest amount of the "daughter" nuclide which you can detect. You would not conclude that the sample was "old."


The realities of the laboratory, of course, mean that there are no sharp cut-off points. Instead, there will be ranges, and at the extremes the results can only give a rough maximum or minimum age. Dates landing in that zone would be considered unreliable.


It's a little like weighing a flea on a truck scales or weighing a brick on a scales designed to weigh envelopes. If the brick depresses the envelope scales all the way to the highest mark, you conclude that the brick weighs at least that much. If the flea doesn't depress the scales at the truck stop, you conclude that it weighs less than a weight which barely moves those scales.


Consequently, the choice of scales will not dictate the result. Of course, if the truck scales isn't perfectly calibrated, you might get a 50-pound flea! Similarly, the envelope scales would indicate that the brick only weighs a few ounces. However, no one who is familiar with such scales would take those readings too seriously. A similar situation holds for radiometric dating. Readings falling in the minimum or maximum zones are not taken too seriously. Thus, there is no problem.


Was that so difficult?

Polystrate Fossils and Out of Order Strata Layers

How Good Are Those Young-Earth Arguments?
A Close Look at Dr. Hovind's List of Young-Earth Arguments and Other Claims
by Dave E. Matson
Copyright © 1994-2002


Hovind: Poly-strate fossils, missing layers, layers out of order, misplaced fossils, and layers in reverse order all invalidate the geologic column.

None of these charges amount to a hill of discarded beans. We can't examine every such claim, but we can look at a few examples.


Poly-strata fossils.


By this, Dr. Hovind means fossils which cross several strata. Usually that means fossilized, vertical tree trunks. Creationists are attacking a straw man. No geologist claims that every little stratum requires thousands of years to be laid down! The strata associated with polystrate fossils invariably show evidence of relatively rapid deposition.


'Polystrate' trees show every sign of extremely rapid burial, generally when rivers flood over their banks.


(Eldredge, 1982, p.105)


An example of this very thing is given by Dunbar and Waage (Dunbar & Waage, 1969, p.52). They show a photo of the Yahtse River area in Alaska, which depicts a number of upright, broken-off stumps stripped of most of their branches. The taller stumps poke out above the alluvial mud. This is the result of natural processes accompanying river course change. A couple of pages later we find a photograph showing how trees can be buried fairly quickly in another way. In this case, volcanic ash has partially buried a forest whose trees are mostly reduced to broken-off stumps stripped of their branches. Continuing volcanic eruptions over a period of years (dead trees last a long time!) and the interaction with wind would create variations in the strata which finally bury the stumps.


In some cases, burial might well be less than instantaneous. In the San Francisco area fossils of cedar and redwood (dated at 23,000 years) are found in place 20 feet below present sea level. This may be due to a rising sea level from melting ice-caps. (Encyclopedia Americana, 1978 Annual [Geology].) A similar find exists off the coast of Japan where remnants of a forest of willows and alders are found in 70 feet of water. They are some 10,000 years old (Chorlton, 1984, p.90).


Thus, we have polystrate fossils in the making, without the aid of Noah's flood.


As to the 80-foot whale, standing on its tail, which was found by the GREFCO Corporation near Lompoc, that being an outstanding example of a polystrate fossil, you may rest assured that geologists do not assume that it remained on its tail until slowly buried by diatoms! More likely it died a natural death, sank to the bottom for a time, and was buried in some kind of underwater avalanche which left it in its vertical position. Here's what a Christian geologist had to say:


Before the discovery of rapid, submarine sediment flows the circumstances under which these animals were buried was very much a mystery...


...it is logical to conclude that the Lompoc diatom beds were deposited naturally on the ocean floor, and that sometime before the period of tectonic activity which finally raised them to an elevation above sea level the earthquakes in that area triggered at least one large sediment slide and flow which overwhelmed and buried the animals that were down-slope from where the slide began. As pointed out in the early parts of this section on rapid burial, we now know of large sediment flows in various parts of the world which apparently had all of the characteristics necessary for overwhelming and burying both swift and large marine animals.


(Wonderly, 1987, pages 56,58)


The original source of our story appears to be K. M. Russel, who wrote an article in Chemical and Engineering News (Oct. 4, 1976). Some "facts" were wrong from the start. To begin with, the whale fossil was not buried vertically. The angle was more like 40-50 degrees from the horizonal. Most importantly, the skeleton lay parallel to the bedding plane, meaning that the site was, more or less, once a level sea floor. The discovery of hardground horizons within this strata make it clear that for long periods of time this was, indeed, the ocean floor and not a quick load of sediment from Noah's flood. The fossil was buried by the same kind of diatomites that accumulated in deep bays and basins along the Pacific Coast during Miocene times.


These sediments lack any sedimentary structures that would indicate catastrophic deposition. Rather, the strata exhibit laminations indicative of slow accumulation on an anoxic bay bottom.


(Darby South, Internet)


Indeed, a partially buried, fully connected (articulated) whale skeleton is slowly being buried even now off the California coast! It was discovered about 10 years ago by a deep-sea submersible.


Plate tectonics wrote the final chapter. As the Transverse Ranges were being folded and pushed up, the sea floor on which our whale had settled and, in time, had been buried, was now subject to folding. As a result, that whale skeleton became tilted along with the strata on which it lay. Now that we have the real facts, we can see that this whale fossil is actually a good reason for rejecting Noah's flood as the source of the geologic column! Funny, how creationists often shoot themselves in the foot while trying to attack conventional geology!


In order to collect the point, creationists must show that polystrate fossils exist where they shouldn't be. That involves a lot more work than conjuring up interesting pictures and local stories accompanied by much speculation.


Missing Layers


Missing layers are no problem at all once one understands that the geologic column is an abstract conceptual tool, an ideal reference frame, which gives order to the overall geologic record. It's like a dictionary listing the more important English words. No one expects that every one of those words will be present in some history book! Neither does the geologist expect any particular locality to exhibit all the known strata.


Has it occurred to you that the thick strata now being formed in the oceans off our coasts are not forming on the mainland? Thus, we have one cause of our missing strata, namely that it might not have been laid down in the first place! The late Jurassic, for instance, was not laid down everywhere; where land existed no sediment was being added, except in lakes, dune accumulations, and in certain other situations. Another possibility is erosion. Given enough time, erosion will strip away exposed strata. Large parts of Canada have been, with the help of glaciers, stripped all the way down to the Precambrian rock! Talk about missing layers!


Again, missing strata present no problem for geologists. The geologic column has no missing strata because it is a catalog of all known strata; it is not a physical locality but a chronological compilation of all localities, an ideal reference frame.


Out of Order and Reversed Layers


"Overturning of strata is associated with intense folding in tectonic belts formed by continental collision." (Strahler, 1987, p.384) Anyone who makes the most elementary observations of mountain strata will note a high degree of folding. Anyone who has studied a decent geology text, a result of numerous years of careful work by thousands of trained geologists who made numerous field trips to assorted mountains and valleys in order to chip away at the earth's old rind, will appreciate just how messy things can get.


Nevertheless, except in the very worst cases of mangled rock, there is almost always a pattern to it which holds the key to its history. The Grand Morgon in the French Alps, for instance, has a recumbent fold giving a strata sequence like D-C-B-A-B-C-D. Common sense suggests that the strata have been folded, and careful mapping bears that out. Footprints, mudcracks, ripple marks, cross laminations, and various other clues found on the surfaces of bedding planes often confirm beyond any shadow of a doubt that a given sequence of strata have been overturned.


A strata sequence of B-C-A-B-C, to give another example, suggests that the strata A-B-C had been shoved upon itself after breaking along a front, and that stratum A- had eroded away. A geologist studying the site would look for evidence of an overthrust at the boundary of C-A. To hear creationists complain, you'd think the strata were shuffled like a deck of cards without a clue as to which way is up! Far from it! A careful mapping of an area is usually enough to unravel the mystery or at least point to a likely solution. Strahler (1987, Chapter 40) provides an excellent discussion on the nature of overturned strata, including a thorough discussion of the Lewis Overthrust.


When geologists look at areas which haven't been seriously disturbed for great ages, such as the Grand Canyon, they always find the strata in the right order. Some strata may be missing, but the order will be correct. Such studies soon made it abundantly clear to the early geologists that the earth's strata has a very specific order. Thus arose the concept of the geologic column.


Let me also add that radiometric dating supports only one order for the geologic column, the same order found in undisturbed areas. Radiometric dating, where applicable, also clearly identifies reversed strata and other anomalies. Such anomalies, as already noted, can often be identified by extended mapping of an area.


More evidence illustrating the correct order of the geologic column may be had by mapping the bottom sediments of the Atlantic Ocean according to their geologic ages. If we move away from the Mid-Atlantic Ridge, either towards the United States or North Africa, we move successively from the recent sediments of the Quaternary period to the Pliocene, Miocene, Oligocene, Eocene, and Paleocene epochs, which make up the Tertiary period, to the late, middle, and early Cretaceous periods, and finally into the late Jurassic period just beyond the continental shelves of either coast (McGeary and Plummer, 1994, p.79). The fact that these sediments are in perfect textbook order is hardly surprising since the Atlantic sea floor has been continually spreading apart since the late Jurassic. As new sea floor emerges and spreads outward it picks up the most recent sediment, which means that the farther away we look from the Mid-Atlantic Ridge the older the sediment is in the bottom layer. We should, therefore, find the whole textbook sequence (as far as it goes) in its proper order as the sea floor is a perfect place for the continuous deposition of sediment, and that is exactly what we do find!


A similar story holds for the East Pacific Ridge, which runs roughly south of central Mexico. If we move northwest towards the Marianas Islands (south of Japan) we cross the same order of geologic epochs and periods as we did in the Atlantic! Again, this is not surprising since the Pacific sea floor is spreading out from that ridge, meaning that it would also record the true order of sediment deposition. Naturally, it will agree with the order found in the Atlantic. Further confirmation, if needed, can be found in the Mid Indian Ocean Ridge (McGeary and Plummer, 1994, p.79). There is really no question whatsoever as to the proper order of the world's major strata. It is a sign of sheer desperation that today's creationists would even try to challenge such a solidly established fact as the geologic column.


d) Misplaced Fossils


The creationist claim of misplaced fossils, i.e., fossils (or manufactured items) in the "wrong" strata, is scarcely more than a collection of dime-a-dozen rumors that are completely lacking in scientific documentation. The one, shining exception, the supposed man-tracks along the Paluxy River in Texas, which had enough "substance" to be the subject of a creationist movie, has proved to be an embarrassing bust. It is an embarrassment to all but the most die-hard, head-in-the-sand creationists. A thorough discussion of all the claims for "misplaced" fossils and manufactured items would fill an entire book. We can only scratch the surface.


Carl Baugh's hammer: This hammer was supposedly dug out of Ordovician strata. In fact, it is a 19th century miner's hammer of recent American historical style.


Carl Baugh is something of an embarrassment even to creationists in that he is continually finding things in the Paluxy River area which just ain't so! Perhaps you've heard of "Glen Rose Man" which was created from a fish's tooth! That was one of Baugh's productions. As for the hammer, which was actually found by others near London, Texas in the 1930s, supposedly in an Ordovician stone concretion, it merely came into Baugh's possession.


The stone concretion is real, and it looks impressive to someone unfamiliar with geological processes. How could a modern artifact be stuck in Ordovician rock? The answer is that the concretion itself is not Ordovician. Minerals in solution can harden around an intrusive object dropped in a crack or simply left on the ground if the source rock (in this case, reportedly Ordovician) is chemically soluble. This is analogous to stalactites incorporating recent objects in their paths as they grow. The rapidity with which concretions and similar types of stone can form is evident in soil caliche development. "Rapid formation of limestone has been shown in coral atolls in the Pacific where World War II artifacts have been found in the matrix" (McKusick and Shinn, 1980).


(Cole, 1985, pp.46-47)


Given the above data, evolutionists are scarcely troubled by Carl Baugh's hammer.


Paluxy River Footprints: For years creationists claimed that human footprints could be found side by side with dinosaur prints at this site near Glen Rose, Texas. The complete story of creationist doings in and around the Paluxy River is, with one or two notable exceptions, a classic study of wishful thinking gone awry. Few studies shed more light on the creationist mentality than does the history of the Paluxy River "mantracks." Richard Tierney (1986) captures some of the flavor of that story which is too long to tell here. A running account can be found in various issues of Creation/Evolution.


There was even a seductive creationist movie, Footprints in Stone, which "documented" the "mantracks" found along the Paluxy River. Laurie Godfrey (1981) showed that the film was pseudoscientific. The "man prints" in the film had been darkened, with either shellac or oil, making them look far more human than they would have otherwise (Godfrey, 1981, p.24). In some cases the "man print" was a portion of a larger footprint which was probably made by a dinosaur. "In other cases the shellac seemed to connect erosional depressions." (Godfrey, 1981, p.24). One of Godfrey's students wrote to Eden Films to ask whether or not duplicates of their casts could be purchased for firsthand examination. Their answer was "no, not yet," leaving Laurie Godfrey wondering "Why not yet?" Perhaps a careful examination of such casts would have exposed the wishful thinking, expressed in shellac outlines, that went on. Dr. Coombs, a vertebrate paleontologist who has studied dinosaur tracks, and Dr. Gomberg, an expert on the anatomy of the primate foot, both watched the film and concluded that they saw no genuine human tracks except those made during a modern demonstration. They concluded that some of the prints shown were genuine in the sense that some kind of animal made them, but the details from the film were too poor to draw any conclusions.


It is fortunate that some Texas paleontologists have examined firsthand the Glen Rose tracks. Wann Langston, Jr., pointed out that some of the "man prints" have distinct claw marks emanating from what the creationists call their "heels." (The creationists apparently reversed the direction of travel for these critters.) Langston also noted that one of the most widely reproduced footprint photos of Paluxy man shows a portion of a poor print of a tridactyl dinosaur; this may be clear, however, only to someone who, having studied the anatomy of the dinosaur foot, knows what to look for. Milne [1981] makes the same point using photographs of in situ "man prints" taken directly from creationist literature. These "man prints" are nothing more than dinosaur toe impressions, selectively highlighted, with sand obscuring places where the rest of the dinosaur's foot might show. ... The existence of claw marks on some of the best series of "giant man prints" is now acknowledged by creationist John D. Morris, son of Henry Morris and author of Tracking Those Incredible Dinosaurs and the People Who Knew Them. This includes the McFall track, which is shown in Footprints in Stone.


(Godfrey, 1981, p.25)


After commenting on the film's unbalanced testimonials from supposed "experts," a group of commentators that did not include a single vertebrate paleontologist or paleoichnologist (an expert on the tracks of extinct critters), Laurie Godfrey concluded: "In short, the film is a distorted pseudodocumentary, which belongs in the realm of science fiction rather than science."


Before long others had visited the site. Issue XV of Creation/Evolution is devoted to the Paluxy River footprints. In it the studies/reports of R. J. Hastings, L. R. Godfrey, J. R. Cole, and S. D. Schafersman are devastating. "Man tracks" turned out to be erosional features and partial dinosaur prints. A study of stride length added additional support to the obvious. Nor has previous paleontological studies of the area offered any hope for creationists. Fossils typical of the Cretaceous were found in the Cretaceous strata. Mammoth remains were found above that strata in recent deposits, but never embedded in the Cretaceous. The Ryals Trail, the McFall site, Taylor's Trail, and other items were examined and discounted as human trackways or footprints. The details of these studies are too numerous to repeat here.


In September of 1984 Glen Kuban and Ronnie Hastings noticed that coloration patterns, due to secondary infilling of the original depressions, patterns previously noticed on only some of the Taylor site tracks, now appeared on tracks of all four alleged human trails. The coloration clearly brought out the dinosaurian nature of the "human" footprints! A few creationists became so hysterical that they actually hinted that evolutionists might have painted in these markings! Taylor was so impressed with Kuban's guided tour of these problems that he withdrew the film Footprints in Stone from public circulation! (Schadewald, 1986, p.6) The Institute for Creation Research halfheartedly backed off without giving Glen Kuban any credit for his work, which blew the lid off the whole affair. (Schadewald, 1986, p.7).


In the March 1986 Acts and Facts, an anonymous author (presumably Henry Morris) defends John Morris' half-hearted retraction in an unapologetic apologetic. Regarding John Morris' hints about fraudulent colorations, the anonymous author of "Following Up on the Paluxy Mystery" notes that "no evidence of fraud has been found, and some hints of these dinosaur toe stains have now possibly been discerned on photos taken when the prints in question were originally discovered." Glen Kuban, who pointed out these colorations in the early photos, is not mentioned at all. Indeed, the original creationist interpretation of the trackways is characterized as "not only a valid interpretation but arguably the best interpretation of the data available at that time." The "close-minded" evolutionists who have criticized the Paluxy tracks are mentioned only with sneer and smear.


Another creationist organization with a heavy stake in the Paluxy River footprints is the Bible-Science Association. The Reverend Paul Bartz, editor of the Bible-Science Newsletter, has hotly defended Footprints in Stone and editorially sneered at the work of the "Raiders." After Films for Christ withdrew Footprints in Stone, I watched the Bible-Science Newsletter for a reaction. Nothing. The BSA headquarters are in Minneapolis, and BSA officials are active in the Twin Cities Creation-Science Association. I attended TCCSA meetings to hear what the BSA had to say in that forum. Nothing. I privately showed BSA field director Bill Overn an unpublished manuscript on the tracks. About a month later, the BSA finally broke its silence.


(Schadewald, 1986, pp.8-9)


The statement made no mention of Kuban's work or of the contribution that the "Raiders of the Lost Tracks" had made. Schadewald referred to it as "whitewash as usual from the Bible-Science Association," but he held out hope that they would yet come clean. Meanwhile, as if nature intended to add insult to injury, the colorations were becoming more and more distinct as the years rolled by! The "human" footprints were turning into dinosaur footprints! Glen Kuban (1986, pp.15-17) discusses the coloration at some length, noting that:


The colorations provide strong confirmation that all the trackways on the Taylor site are dinosaurian. Even before these colorations became more prominent, the tracks did not merit a human interpretation.


(Kuban, 1986, p.17)


The upshot of all this is that many creationists, at least the more sophisticated ones, have had the good sense to abandon this argument. (Hopefully that includes Dr. Hovind.) The die-hards, of course, continue to dream of finding their Holy Grail along the Paluxy River, a find which will magically banish evolution along with 120 years of scientific study. I wouldn't be a bit surprised if a few of them are still poking around the Paluxy River even today. Thus, from time to time, we may expect pathetic attempts to rejuvenate the Paluxy River juggernaut which had sunk of late. Stay tuned!


Trilobites and Humans: Dr. Hovind has a slide of a trilobite which was "stepped on" by a human!


This looks suspiciously like one of the bogus Meister tracks (Conrad, 1981, pp.30-33). Mr. William J. Meister's specimen, found in 1968 near Antelope Springs, Utah, was offered as evidence that a trilobite was stepped on by a human wearing a boot with a heel. In a 1973 debate Reverend Boswell claimed that it had been tested by three laboratories around the world!


Sounds pretty impressive, huh? In fact, it is nothing more than a slab of Wheeler shale that has a fragment spalled off in the form of a footprint, which reveals a trilobite, Erathia kingi. To fully appreciate that fact, which has been established beyond any reasonable doubt, you should read Conrad's account.


The Olmo, Castenedolo, and Calaveras Skulls: Creationists have made some interesting claims about these fossils. In his book, the Handy Dandy Evolution Refuter, Robert Kofahl stated that the above fossils were essentially modern and yet were found buried in very old strata. In The


Creationist Explanation, Kofahl and Kelly Segraves suggest that the above fossils were relegated to dusty museum closets and forgotten because they didn't fit the evolutionary scheme. Scientific Creationism, one of Henry Morris' classic works, states that the Castenedolo and Olmo skulls were found in undisturbed Pliocene strata in Italy. The Bible Science Newsletter had this to say (from: Conrad, 1982, p.15).


Another example of how people react when the evidence does not agree with their philosophical position is the treatment which the Castenedolo skull received. This totally modern type skull was found in Pliocene strata, dated at one-half million years. Because this discovery did not agree with preconceived ideas, it is rarely mentioned in textbooks or other literature. (p.5)


As the professional creationist watcher might suspect, there was more to the story. Conrad (1982, p.16) fills us in with a quote from the 1957 issue of Fossil Men, by Boule and Vallois:


The bones from Castenedolo, near Brescia in Italy, belong to several skeletons of men, women, and children and were found on various occasions in a shelly bed of sand and clay, of marine origin and of Pliocene age. In 1899, the discovery of a new human skeleton was the subject of an official report by Professor Issel, who then observed that the various fossils from this deposit were all impregnated with salt, with the sole exception of the human fossils... It seems certain that at Castenedolo we are dealing with more or less recent burials.


(Boule and Vallois, page 107)


Ernest Conrad goes on to inform us that in 1965 collagen tests demonstrated "that the Castenedolo materials were intrusive burials into the Astian clays." Radiocarbon dating in 1969 by the British Museum placed the cranial fossils in the Holocene. We're dealing with relatively recent fossils and they present no problem for evolution.


The creationists are also mistaken about the Olmo skull:


In the case of the Olmo materials, the creationists are in error from the beginning. The Olmo skull fits perfectly into the evolutionary chronology and is a legitimate specimen, for here we find a modern skull cap in upper-Pleistocene gravels--exactly where it ought to be.


(Conrad, 1982, p.16)


Based on various lab tests developed by the British Museum, it was determined that the Olmo skull was probably from the upper Pleistocene. It was relatively old, but it presents no embarrassment for evolution. It came from the Upper Paleolithic cultural period.


The Calaveras skull turned out to be a hoax! If you wish to read the details, see Conrad (1982, pp.17-18). Thus, Morris, Kofahl, and Segraves were taken in by a hoax! Take note, those of you who speak of Nebraska Man!


Neanderthal Man in Louisiana?: Why is it that skeptics like to see such claims documented in good, scientific journals? Take the case of the 11-foot Neanderthal Man, whose fossil was supposedly unearthed in Louisiana. This case, which was researched by Paul V. Heinrich, was sent to me by Ed Babinski via the Internet.


In 1951 the Morning Advocate stated:


A gravel contractor unearthed parts of a human skeleton 35 feet from the surface of the ground and an LSU geologist said today the bones may be prehistoric. ... J. W. West, of LSU and several student scouts viewed the bones but called their finds too inconclusive to make an official statement.


(Morning Advocate, January 9, 1951)


The above story was distributed all over the U. S. by the Associated Press. The State Times (now defunct) put it this way:


Sicily Island, Jan. 9, (UP) - Anthropologists and geologists studied today a collection of bones from a gravel pit that may show that the Neanderthal Man - an 11-foot tall ancestor of modern man - lived in North America about 50,000 years ago.


If so, it may cause revolutionary changes in anthropological thinking. ...


(State Times, Jan. 9, 1951)


Thus, we seem to have evidence for 11-foot giants roaming about Louisiana as documented by bones from the Plio-Pleistocene Citronell Formation within Louisiana. Unlike similar creationist stories, which are often extremely vague, this account comes with details. The specific geological formation is identified along with at least one of the scientists involved. We are even told that the site is about 5 miles west of the small town of Sicily Island. As Paul Heinrich noted, "Had the bones not been donated to and catalogued in the LSU Museum, another anomalous fossil human skeleton would have appeared on the scene." Creationists would have had a field day! "... shows like 'The Mysterious Origins of Man' and books like 'Forbidden Archaeology' would have had an example of 'human remains' of Plio-Pleistocene age being found in Louisiana and ignored by myopic paleontologists and archaeologists."


As it happened, those bones were donated to the LSU Museum and catalogued. Several years later they were examined in detail and proven to be those of a bear (Arata and Harmann, 1966). The newspapers and wire services lost interest and dropped the story. Newspapers are written to entertain their readers, not to set facts straight.

Column invented to discredit Bible and does not exist

How Good Are Those Young-Earth Arguments?
A Close Look at Dr. Hovind's List of Young-Earth Arguments and Other Claims
by Dave E. Matson
Copyright © 1994-2002


Dr. Hovind: The fictitious geologic column (invented in the 1800's to discredit the Bible) does not exist anywhere in the world except in textbooks.

Oh, sure, those early creationists invented the geologic column to discredit the Bible! That just makes loads of sense, doesn't it? Is it possible that Dr. Hovind, who taught earth science for 13 out of his 15 years as a high school science teacher, doesn't understand the concept behind the geologic column? The thought boggles the mind! On top of that, Dr. Hovind is simply wrong in his claim that no place on Earth has a full set of representative strata.


John Woodmorappe, a young-earth creationist, has admitted that representative strata from the Cambrian to the Tertiary have been discovered lying in their proper order in Iran, by the Caspian, the Himalayas, Indonesia, Australia, North Africa, Canada, South America, Japan, Mexico, and the Philippines! (Woodmorappe, 1981, p.46-71. See especially, pp.62 & 67). Furthermore, Glenn R. Morton, a professional geophysicist, has reported that portions of Alaska also contain strata representing all these geologic periods lying in their exact textbook order. (Phone conversation between Edward Babinski and Glenn Morton, as relayed to me.) Sometime later he identified three wells for me in McKenzie County, North Dakota, which had penetrated all the geologic periods in their correct order. Morton also indicated that the East China Sea, the Juixi (pronounced jewshi) basin in China and many more areas could be added to the list. So, the geologic column definitely does exist! That is to say, there are a number of locations where every period of the geologic column from the Cambrian on up is present and in proper order. (Wherever we find relatively undisturbed areas without any of the obvious signs of mountain building, that strata is always in the textbook order. Some of the geologic periods may be missing, either because they were never laid down at that location or because they have since eroded away. However, the relative order of those present is preserved. See Topics G4b and G4c for a discussion of missing and out-of-order strata.)


Showing that the geologic column is fully represented in various places is not my main concern here. Far more important is Dr. Hovind's fundamental misunderstanding of the geologic column, which seems to be shared by many creationists.


The geologic column is an ideal, complete, chronological reference frame that defines the status of those strata having (more or less) a worldwide distribution or correlation in time. For example, local strata that can be traced to places where it lies above strata of the Mississippian Period, and to other places where it lies below strata of the Permian, or which can be dated or identified as belonging to that interval, is defined as belonging to the Pennsylvanian (American) or Upper Carboniferous (European) Period. Of course, we are assuming the usual order here. Allowances must be made for overturned strata, etc.


In the geologic column (American version), the Pennsylvanian Period is the sixth period in the Paleozoic era and is characterized in many places by great coal-, oil-, and gas-bearing deposits. It contains the record of the first reptiles, etc., etc. The geologic column is like a yearbook with the pictures of all the graduating students in it. No one expects that every one of those students will show up for a particular dance! Neither does the geologist expect that some locality must exhibit all the known strata.


The point is that the earth's strata has a very definite chronological order to it, and that order, taken at its most complete, ideal form, serves as an abstract reference frame for defining the actual strata of each locality. The question as to whether some locality has all the periods in the geologic column is only of academic interest; it has no bearing on the fitness of the concept.


That is usually what is meant when one refers to the geologic column. If not that, then the phrase is simply being pressed, rather loosely, as another name for the strata of some locality or localities.

Geological Column and Evolution

How Good Are Those Young-Earth Arguments?

A Close Look at Dr. Hovind's List of Young-Earth Arguments and Other Claims

by Dave E. Matson

Copyright © 1994-2002


Dr. Hovind: The entire geologic column is based on the assumption that evolution is true.

If Dr. Hovind would take the trouble to do a little reading from something other than creationist publications he would not make such an outrageous statement. I believe he has confused the use of index fossils with evolution. One creationist editor, who is more mellow than his unfortunate statement suggests, phrased the argument thus:


Unfortunately the geologists date the rocks as the paleontologists tell them to. Then the paleontologists use the geologists' dates as evidence for the age of the fossils! That's not science. That's just a game played by dishonest scientists!


That passage might have come out of one of Henry Morris' books, except that Morris usually avoids crude slander.


Perhaps Dr. Hovind is not aware of the fact that by 1815 the broad outlines of the geologic column from Paleozoic times onward had been worked out by people who were mostly creationist geologists. The relative order of the strata was first determined by the principles of stratification. (The principle of superposition was recognized as early as 1669 by Steno.) Reverend Benjamin Richardson and Reverend Joseph Townsend were a couple of early geologists involved in this work. By 1830 Lyell's famous textbook, Principles of Geology, came out. The captain of the H.M.S. Beagle, a very strong Bible believer, made it a point to have a copy of Lyell's book for the ship's library. Obviously, even Lyell was not pushing evolution at the time. Such was the age of the great creationist geologists!


The principle of faunal succession in the geologic record was established by direct observation as early as 1799 by William Smith. By the 1830's Adam Sedgwick and Roderick Murchison established a correlation between the various types of fossils and the rock formations in the British Isles. It was found that certain fossils, now referred to as index fossils, were restricted to a narrow zone of strata. Studies done on the European continent soon demonstrated the universal validity of index fossils. That is, an index fossil corresponded to a very specific point in the geologic column. Once the worth of index fossils had been established on the basis of stratification studies, they could logically be used to extend the correlation of rock formations to other continents. At this point in time they were simply a useful tool for correlating rock formations.


One can hardly accuse these pioneers of evolutionary prejudice. Nearly a half-century would pass before Darwin's book, The Origin of Species, was published! By then, the relative ages (order) of the geologic column had already been worked out in some detail. Radiometric dating would later confirm the relative ages of the strata and tie them to absolute dates. (Far from being a rubber stamp, radiometric dating would go on to revolutionize our understanding of the Precambrian.) Thus, it became possible to date strata directly from index fossils.


Note that evolution has nothing to do with how the index fossils are used to date strata! Any kind of object clearly restricted to a specific point in the geologic column would do just fine. If green dice were found only in the middle Ordovician strata, they would make excellent "index fossils." Evolution should be seen as an explanation of the faunal succession, a succession which was worked out long before evolution dominated the scene. Evolution, working in tandem with geologic ages, can explain why we have index fossils, but evolution is not needed to make the index fossils useful for dating strata.


While we're on this subject, you might wish to know the odds of arranging the Precambrian era, the seven geologic periods of the Paleozoic (Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, Permian), the three periods of the Mesozoic (Triassic, Jurassic, Cretaceous), and the two periods of the Cenozoic (Paleogene, Neogene or Tertiary, Quaternary) in their proper order by pure chance. Your chances are 6.2 billion to one of getting the right order for all thirteen. And, when you consider that each period can also be divided into "upper, middle, and lower," the odds of arranging them in the correct order by pure chance become astronomical. Radiometric dating has passed that severe test! It has correctly placed the Cambrian between the Precambrian and the Ordovician, the Ordovician between the Cambrian and the Silurian, the Silurian between the Ordovician and the Devonian, and so forth.


Creationists, on the other hand, must explain to us how sediment and rock laid down in a mere year can yield such fantastic, orderly differences in radiometric ages. This poses a fatal problem whether one believes in the accuracy of radiometric dating or not! One would think that the flood sediments (gathered from the four corners of the old antediluvian world) and their associated igneous rock (formed during the flood) would all register very little radiometric age. At the very least we would expect random fluctuations if the radiometric methods were totally at sea. Why should the percentage of lead to uranium in zircon crystals (the key to ordinary uranium-lead, radiometric dating) depend on which geologic period they are found in? If most of the geologic column were created during Noah's flood, would it really matter whether a zircon crystal was found in Cambrian strata or Cretaceous strata, in Jurassic strata or Tertiary strata? Noah's flood might just as easily deposit the same crystal in one place as another.


Thus, we have a mystery. Pressure has nothing to do with it, and zircon crystals all have about the same density as their total lead content is small. Just what is it that a Cambrian stratum has which a Cretaceous stratum lacks? What does the Jurassic strata have that the Tertiary strata do not? If rock type mattered then we would expect a zircon crystal's lead content to vary dramatically within the Cambrian or Cretaceous strata according to their local rock types. No, that's not what we observe. How about neutrinos or cosmic rays? Neutrinos penetrate the earth so easily that they would affect all strata more or less equally, to the extent that they affect anything at all. Cosmic rays, on the other hand, don't penetrate that far into the earth to begin with, so we can rule them out. The depth of burial, itself, has little to do with our mystery. In some parts of the world the Cretaceous is found deeper than is the Cambrian in other parts of the world. The depth at which either is found can vary dramatically. In the Grand Canyon area the Cambrian lies beneath a huge column of strata; in California's Mojave Desert portions of the Cambrian are exposed at the surface.


For the young-earth creationist, this is an unsolvable mystery, a mystery with parallels in each of the radiometric clocks used by geologists. The potassium-argon, rubidium-strontium, samarium-neodymium, luteium-hafnium, rhenium-osmium, thorium-lead, and the two uranium-lead dating methods all point to the same amazing fact. The ratio between tiny amounts of radioactive elements and their decay products have this uncanny ability to determine which strata a rock will appear in! What is this magic ingredient that each of the geologic periods have which affects rocks and zircon crystals so? For those who believe that each of the geologic periods were laid down in days or weeks by Noah's flood, the mystery has no intelligent answer. For the rest of us, the answer is as plain as daylight. The answer to our riddle is time. The Cambrian has simply been around a lot longer than the Cretaceous, and the radioactive uranium in its zircon crystals has had more time to decay into lead. The same radioactive elements in different geologic periods will have decayed by different amounts.


Even creationists realize that time is the only answer, but they give that answer a strange twist. They imagine that the radioactive elements decayed much faster in the past! Such claims are mere flights of fantasy with no basis in fact or theory (see Topic R2). Problems abound. For instance, there are many boundaries (unconformities) in the geologic strata that exhibit a sharp change in radiometric age. Thus, zircons that are formed at about the same time in Noah's flood (from intruded magma close to each side of an unconformity, if such quick formation were even possible) would exhibit impossible differences in the decay of their uranium. Figure 2 explores an additional problem that pops up when one monkeys around with the radioactive decay rates.


A few calculations will rule out a fast radioactive decay rate before Noah's flood, thus firming up our intuitive feeling. Based on the present decay rate of U-238, the Cambrian period began about 570 million years ago. Since then the amount of uranium-238 has been reduced a bit (to 91.544% of itself) by radioactive decay. Had the decay rates remained high after the flood or in its later stages, the zircon crystals in the more recent strata (the last strata laid down by Noah's flood) would have "aged" considerably, which is not the case. Furthermore, the zircon crystals had to be created during Noah's flood in order to be "aged" according to the strata in which they were associated. It is too much to assume that each one just happened to be deposited in the right strata. Therefore, at the time of Noah's flood the decay rate had to be at least fast enough to reduce the amount of uranium-238 to 91.544% of itself in one year. If we generously take that minimum decay rate, with no thought of increasing it further as we look back into the past, we can calculate how much uranium-238 had to be present 1656 years before Noah's flood (when the earth was created, according to Dr. Hovind). It turns out that the amount of uranium-238 needed is 3.47 x 1063 times the amount of uranium-238 around at the start of Noah's flood! In other words, if our entire solar system were made of uranium-238 the quantity would not even begin to suffice.


There is nothing like a few calculations to bring out the absurdity in creationist thinking! We may safely rule out the idea that the radioactive decay rates (for uranium-238, and, by quantum mechanical implication, all others) dwindled to their present values from high rates at creation time. An initial U-238 decay rate high enough to do creationists any good also leads to an absurd conclusion. They must now assume that the decay rates were low before Noah's flood, that they became phenomenally high during the start of Noah's flood, and that they dropped to normal after Noah's flood. Such tailor-made assumptions will impress only idiots and fanatics, and there is yet another problem worth mentioning.


Some of the material that has been radiometrically dated, whose dates fully conform to the accepted ages of their place in the geologic column, come from large masses of once-molten rock. Those samples could not possibly have cooled down in the course of a mere year no matter what. (Try a million years!) Thus, any "aging" done on their interior zircons had to occur, by creationist thinking, after Noah's flood. Only then did the inner rock cool enough so that those crystals finally formed. By creationist reckoning, those crystals really formed after the flood and should reflect the normal decay rates! That is, their uranium-238 should show almost no decay at all. To the contrary, their radiometric age is in good agreement with the strata in which they were formed. Thus, even the tailor-made assumptions, to which a few desperate creationists might be inclined, come to naught.


In summary of these latter points, radiometric dating has passed a severe test whereas young-earth creationism flounders, in hopeless knots, on the basic facts of the geologic record.


Creationist History of the World

As Seen by a Zircon Crystal

Illustration of 'Creationist History of the World as Seen by a Zircon Crystal'


(1) In the beginning God created zircon crystals, lots of them, from pockets of molten rock. Fresh zircon crystals are lead-free, because lead just doesn't fit in very well with their crystallization process. Many new zircon crystals, however, do contain uranium-238. Uranium-238 is radioactive and eventually decays into lead, which is trapped in the zircon crystal. Here, we see fresh zircon crystals that have formed in the newly created earth. Their uranium-238 has not yet decayed. All the rock here is Precambrian.


(2) Noah's flood lays down the Cambrian (dark) strata. Molten rock intruded into the Cambrian strata, and new zircon crystals somehow formed quickly at that time. Today, about 8.5% of their uranium-238 has decayed away. Many creationists say that the radioactive decay rates were once much greater than they are today.


(3) Noah's flood lays down its last sediments. Notice, in each of the succeeding layers, that the zircon crystals formed have lost less and less of their uranium (as measured today). The radioactive decay rate must have been dropping fast!


(4) Today's world. Mountains have pushed up, the polar caps have formed, and various other adjustments have happened. Those zircon crystals that formed right after Noah's flood show practically no loss of uranium-238. Strange, this last stage represents about 4,400 years (out of 6000+) by creationist reckoning and, yet, the uranium in its zircon crystals is essentially intact! Perhaps, by the time Noah's flood started, the decay rate had started to slow down dramatically. As the last sediments were laid down near the end of the year-long flood, that rate must have all but stopped compared to its primordial speed.


But wait! If the decay rate only started dropping at the time of the flood, then it s should have done a job on those Precambrian zircons. If 8% of a zircon's uranium was lost during just the Cambrian (after which the decay rate must drop rapidly), then there shouldn't be any uranium left in those Precambrian zircons! After all, radioactive decay has had only a fraction of a year (at its full strength) to work on the Cambrian crystals; it has had up to 1656 years to work on those Precambrian crystals! Yet, they still have a fair amount of uranium.


That means the radioactive decay rate must have been feeble before Noah's flood. It then skyrockets at the start of Noah's flood and drops dramatically even as that flood rumbles on! We might imagine a radioactive decay rate that was extremely high in the uncertain past, one that has dropped to normal values via some sensible curve. However, to imagine a rate that skyrockets from near-normalcy to extreme values just as Noah's flood gets underway, one which then decays precipitously only to suddenly level off near its present value, is clearly a case of special pleading. If we should forget ourselves and let this point slide, we still have all that radiation being released in a fraction of a year, radiation that conventional geology attributes to billions of years! In case you missed the point, that means the radiation would have been billions of times more concentrated than today! Noah and crew would have fried in one, giant nuclear reactor!!


There is, of course, still the minor matter of explaining in detail how molten rock might be injected into sediments raining out of Noah's flood while leaving the patterns actually found. Also, decent zircon crystals could hardly form if that molten rock cooled too quickly.


The alternative is to imagine that those zircons were formed elsewhere and just happened to sort themselves out during the flood, and that they just happened to deposit themselves into the right strata to give the appearance of successive ages!

Dr. Hovind: The assumption that the geologic column is a base from which to calibrate the C-14 dates is not wise.

With a half-life of only 5730 years, carbon-14 dating has nothing to do with dating the geological ages! Whether by sloppiness or gross ignorance, Dr. Hovind is confusing the carbon-14 "clock" with other radiometric "clocks."


The only thing in the geologic record which has anything to do with calibrating carbon-14 dating is the coal from the Carboniferous Period. Being ancient, the C-14 content has long since decayed away and that makes it useful in "zeroing" laboratory instruments. It's just one of the tricks that have been used to make the work a little more precise.

Curve based on too few measurements

How Good Are Those Young-Earth Arguments?
A Close Look at Dr. Hovind's List of Young-Earth Arguments and Other Claims
by Dave E. Matson
Copyright © 1994-2002


Dr. Hovind: The C-14 cannot be accurately measured. It makes up less than one part per million in the atmosphere, and claiming to be able to measure accurately to 7 decimal places is not reasonable.

This is similar to an argument put out by Harold Slusher (1981, p.45). Dr. Hovind adds the bizarre claim that something can't be measured accurately to seven decimal places. Such nonsense is answered by Dr. Dalrymple, an expert in radiometric dating, who noted that: "Modern counting instruments, available for more than two decades, are capable of counting the C-14 activity in a sample as old as 35,000 years in an ordinary laboratory, and as old as 50,000 years in laboratories constructed with special shielding against cosmic radiation. New techniques using accelerators and highly sensitive mass spectrometers, now in the experimental stage, have pushed these limits back to 70,000 or 80,000 years..." (Dalrymple, 1984, pp.86-87).


We can also explore this issue from first principles.


Given that the half-life of carbon-14 is 5730 years, one can calculate that 4 billion C-14 atoms will produce 1 decay per minute on the average. Converting the 4 billion atoms to grams (a nickel weighs 5 grams), we get 0.000000000000093 grams of carbon-14. Consequently, by tallying one click per minute on the Geiger counter, we can measure a whole lot further than 7 decimal places!


A 1-gram, fresh sample of carbon, containing the atmospheric concentration of one ten-billionth percent of carbon-14, will yield about 12 decays per minute. That figure follows directly from the mathematics and, as the atmospheric portion of carbon-14 given above is an approximation, is close enough to Dr. Hovind's present-day figure of 16 counts per minute per gram. Because of atomic bomb tests, the rate is slightly higher today, but the present rate would not apply to animals and plants which died before such tests. One book used a figure of about 13.5 decays per minute per gram for the pre-bomb rate. Consequently, a 64-gram sample of fresh carbon will still give about 7 clicks per minute after 40,000 years. Because of background radiation, that's about as far as one can normally go with this counting method. As noted above, Dr. Dalrymple would extend that to 50,000 years in special laboratories.


Once again, Dr. Hovind has relied on bad data. If you get your information from a creationist source, you'd better triple-check it! Errors get handed down in the creationist literature like the family jewels!


Dr. Hovind: The shape of the curve of the line is based on too few real measurements to be reliable.

It's not clear to me what Dr. Hovind is talking about. If he is referring to the carbon-14 decay curve then he has demonstrated, once again, his ignorance of radiometric dating.


The decay curve is mathematically determined by the fact that every atom of carbon-14 in a sample has the same chance of decaying during each second of time. That much is predicted by quantum mechanics, which is possibly the greatest of our modern, scientific revolutions.


The random character of radioactive decay is a special case of the indeterminacy of quantum theory, as was pointed out in 1928 by George Gamow, Ronald Gurney and Edward Condon. They showed that a particle held inside the nucleus by a "potential barrier" may be able to "tunnel through" the barrier and emerge on the other side, since if the barrier is finite the wave function of the particle is not completely localized and there is a finite probability that the particle will be outside the nucleus.


(Brush, 1982, p.42)


Since we are dealing with millions of C-14 atoms in even the smallest samples, the amount of C-14 remaining with respect to time will be an excellent approximation of an exponential decay curve. Statistics assure us of that. Indeed, it would be absurd to speak of the half-life of a radioactive isotope if it did not have a good exponential decay curve!


Once we have a good approximation of the half-life for carbon-14, its decay curve can be constructed with complete confidence. We don't need Egyptian mummies or what have you at that point. At that point it's just a routine exercise in math. If you want additional assurance that we have the correct half-life, then look at the close correlation between C-14 dates and tree-ring dates (after correcting for variances in C-14 production caused by changes in the earth's magnetic field). The snug fit indicates that the half-life of C-14 is stable and accurately known. Therefore, so is its decay curve.


Today, the half-lives of those radioactive elements used in dating are known to a few percent by careful laboratory study. So, there's no problem in getting an accurate decay curve.

Carbon-14 Accurately Measured

How Good Are Those Young-Earth Arguments?
A Close Look at Dr. Hovind's List of Young-Earth Arguments and Other Claims
by Dave E. Matson
Copyright © 1994-2002


Dr. Hovind: It is very difficult or impossible to prove that a given sample has not been contaminated. Parent
or daughter products could have leached in or out of the sample.

In the case of carbon-14 dating, the daughter product is ordinary nitrogen and plays no role in the dating process. We are only interested in tallying the original C-14 still present in the sample, the surviving "parent" isotope. The C-14 that is incorporated in the carbon structure of cellulose and the other structural materials of living plants and animals is not going to do much migrating after burial. If structural carbon migrated easily there soon wouldn't be any cellulose, lignin, chitin (or other structural carbon compounds) left in the soil! A piece of wood, for example, would soon turn into a formless cloud of graphite or soot in the soil, with perhaps a little ash marking the original shape! Clearly, that is not something which normally happens. Residues or solutions which do migrate can usually be washed out of the structural matrix of the sample with various chemicals.


To put it another way, we might imagine a piece of buried wood as being something like a sponge. Any carbon-containing liquid originally possessed by that sponge might well leak over time and be replaced by something else. However, unless the sponge itself disintegrates, the carbon which holds its fibers together must stay put. Thus, by choosing a sample that is structurally intact, one may rule out any significant loss of C-14. If the liquid impurities in our sponge can be washed and squeezed out, or estimated in some way, then we may be able to date the sponge (structural component of our sample) itself and get a good date even if non-structural carbon-14 had been lost in a manner that would upset the isotope ratio.


A sample, of course, can be contaminated if organic material rich in fresh atmospheric C-14 soaks or diffuses into it. Such contamination may occur in the ground or during the processing of the sample in the laboratory. However, such contamination will make the sample appear younger than its true age. Consequently, with regards to carbon-14 dating, creationists are barking up the wrong tree on the contamination issue!


Laboratories, of course, do have techniques for identifying and correcting contamination. There are various methods of cleaning the material, and the activity of each rinse can be measured. Lab contamination and technique can be checked by running blanks. A careful choice of samples will often minimize contamination. Dating various portions of a sample is another kind of check that may be performed.


Often there are cross-checks. Samples from top to bottom of a peat bog gave reasonable time intervals (Science, vol.200, p.11). The calibrated C-14 method confirmed Egyptian records, and most of the Aegean dates which were cross-dated with Egyptian dates were confirmed (American Scientist, May-June 1982). The marvelous agreement with tree-ring data, after correction for variations in the earth's magnetic field, has already been mentioned.


Carbon-14 dating thus presents a deadly challenge to young-earth creationists. If an old date is reasonably accurate, they're out of business; if an old date is bad due to contamination, then they are still out of business because the true date is most likely older still. It hardly seems fair, but that's the way it is. With that in mind, let's look at a few carbon-14 dates.


Egyptian barley samples have been found which date to 17,000-18,300 years old (Science, April 7, 1978). On page 1346 the author explains some of the professional care which stands behind his use of the carbon-14 method.


A wooden walkway buried in a peat bog in England has been dated to about 4000 BC by the carbon-14 method (Scientific American, August 1990, p.30). Odd, that Noah's flood neither destroyed it nor deposited thick sediments on top of it! Jennifer Hillam of the University of Sheffield and Mike Baillie of Queen's University of Belfast and their colleagues were able to date the walkway by a second method, i.e., tree-ring dating. They found out that the walkway, known as the Sweet Track, was built from trees felled in the winter of 3807-3806 BC. Pretty close agreement, huh?


Stonehenge, as dated by carbon-14, was built over a period from 1900 BC to 1500 BC -- long before the Druids came to England. Astronomer Gerald Hawkins found, after careful computer calculations, that the arrangement of the stones at Stonehenge are aligned with key positions of the sun and moon as they were almost 4000 years ago. (Weber, 1982, p.29). Thus, we have another remarkable confirmation of the C-14 method.


When did the volcano that destroyed Thera (and probably the Minoan culture as well) explode? Radiocarbon dating of seeds and wood buried in the ash, done by scientists at the University of Pennsylvania, pointed to no later than 1600 BC. Being that this was one of the biggest volcanic eruptions in recorded history, it almost certainly caused worldwide cooling which would, in turn, affect tree growth. Sure enough, the growth rings among oaks buried in Ireland's bogs show the effect of unusual cooling from 1628-1618 BC. Nor was that just an effect of local weather conditions. The bristlecone pines in the White Mountains of California show the same thing. A third estimate came from studies in Greenland. "In 1987 Danish geologists examining signs of volcanic acidity in the Greenland ice sheet concluded that the Thera volcano erupted in 1645 B.C., give or take 20 years." (Biblical Archaeology Review, Jan/Feb 1991, p.48). Thus, we have a remarkable agreement between three different methods, all within two or three percentage points of each other!


Trees buried by the last advance of glacial ice at Two Creeks, Wisconsin were dated at 11,850 years. (Strahler, 1987, p.251). Between those trees, which are buried in Valders red till, and an earlier, deeper layer of till, the Woodfordian gray till, lay the remains of a forest bed! What is a forest, including developed soil and rooted stumps, doing between two advances of ice? That could be an interesting question for someone who believes in only one "ice age." In 1878 Baron Gerard de Geer, a Swedish geologist, made a careful study of the annual varves left in European glacial lakes. By careful counting and cross-checking he was able to determine that the oldest glacial lakes, which would have formed at the start of the retreat of the ice, were 12,000 years old. Thus, we have a rough check between varves in glacial lakes and radiocarbon dating.


Richard Foster Flint, a professor of geology at Yale University and an expert on the Pleistocene epoch, was among the first to apply radiocarbon dating to glacial events. Collecting wood, bones and other organic material that had been covered over by the Laurentide Ice Sheet as it plowed across eastern and central North America, Flint collaborated with geophysicist Myer Rubin to demonstrate in 1955 that in most places the ice sheet achieved its greatest advance about 18,000 years ago, began to withdraw shortly thereafter and then hastened its retreat about 10,000 years ago.


(Chorlton, 1984, p.120)


Ancient cave art, at cueva de los caballos, near Castellon, Spain has been dated at about 6000 BC (The Times Atlas of World History [1978]).


On the wall of Gargas Cave in the French Pyrenees are the outlined hands of Ice Age artists which date to at least 12,000 years. Magnificent prehistoric cave art, comparable to that of the world-famous caves of Altamira, Spain and Lascaux, France, was recently discovered in southern France, in the Ardeche River canyon area (Los Angeles Times; Pasadena Star-News January 19, 1995). Its 300 paintings of such animals as bison, reindeer, rhinoceros, woolly rhinoceros, a panther, an owl, a hyena, bears, lions, horses, wild oxen, mammoths, wild goats and other animals is estimated to be between 19,000-22,000 years old. Sorry, no dinosaur drawings were reported! In Europe, cave art was at its height around 20,000 years ago. Some examples probably go back 30,000 years!

Carbon-14 - An Accurate System

How Good Are Those Young-Earth Arguments?
A Close Look at Dr. Hovind's List of Young-Earth Arguments and Other Claims

Dr. Hovind (R3): The initial C-14 content cannot be known. Different parts of the same sample often yield different ratios of C-14/(carbon-12) C-12. Various living samples give very different ratios.

With at least one notable exception on the books, plants and animals get their carbon-14 from the atmosphere. Plants take it in directly, and animals eat the plants. Thus, it gets passed up the food chain. It is not surprising, therefore, to find that the carbon-14 in living plants and animals is in reasonable equilibrium with the atmospheric carbon-14. Some creationists, however, have claimed that certain plants can reject carbon-14 in favor of carbon-12. Because of the chemical similarity of carbon-14 and carbon-12, it is unlikely that such plants could deviate much from the ratio of C-14 to C-12 found in the atmosphere. Neither freak cases nor small deviations pose much of a problem for radiocarbon dating, which, after all, works well with a wide variety of plant and animal species. Hence, we only have to worry about the initial concentration of C-14 in the atmosphere. Carbon-14 Decay Rate shows that the level of C-14 in the atmosphere has not varied appreciably over tens of thousands of years. Therefore, the initial C-14 content is known for any reasonable sample!


The notable exception involves certain mollusks, which get much of their carbon from dissolved limestone. Since limestone is very old it contains very little carbon-14. Thus, in getting some of their carbon from limestone, these mollusks "inherit" some of the limestone's old age! That is, the limestone carbon skews the normal ratio between C-12 and C-14 found in living things. No problem! If one dates such mollusks, one must be extra careful in interpreting the data. Not every mollusk shell presents such problems, and the dating of other material might yield a cross-check. Further study might even allow correction tables. The discovery has strengthened the carbon-14 method, not weakened it! By the way, shouldn't the creationist be worried over the old, carbon-14 age of the limestone? Why is it that limestone has so little C-14 in it?


Different parts of the same sample may, indeed, yield different C-14/C-12 ratios. Partial contamination, say of a block of wood, may affect its different parts to different degrees. Insect burrows, cracks, and partial decay may allow contamination later on to affect those portions of the sample unequally. However, there are laboratory techniques, often ingenious, for dealing with such problems. If the sample shows evidence of being hopelessly contaminated it is pitched.


Some samples, such as a section of a tree trunk, may well contain material of considerably different ages. The interior portion of a tree trunk could easily be several hundred years older than the outer portions. Once again, the C-14/C-12 ratios would reflect this difference in age.


In summing up this point, we do know within good limits what the initial C-14 was for any reasonable sample. A sample will not have different ratios of carbon unless it has been contaminated or reflects a genuine range of ages.

Carbon-14

How Good Are Those Young-Earth Arguments?
A Close Look at Dr. Hovind's List of Young-Earth Arguments and Other Claims
by Dave E. Matson
Copyright © 1994-2002


Dr. Hovind (R2): The C-14 decay rate is not constant. Several factors, including the 11-year sunspot cycle, affects its rate of decay.

It is painfully obvious that Dr. Hovind knows next to nothing about carbon-14 dating! Changes in the sunspot cycle do have a noticeable, short-term effect on the rate of C-14 production inasmuch as sunspots are associated with solar flares, which produce magnetic storms on Earth, and the condition of the earth's magnetic field does affect the number of cosmic rays reaching the earth's upper atmosphere. (Carbon-14 is produced by energetic collisions between cosmic rays and molecules of nitrogen in the upper atmosphere.) Sunspots have absolutely nothing to do with the rate of C-14 decay, which defines the half-life of that radioactive element. Dr. Hovind has confused two completely different concepts.


Quantum mechanics, that stout pillar of modern physics, which has been verified in so many different ways that I couldn't begin to list them all even if I had them at hand, gives us no theoretical reason for believing that the C-14 rate of decay has changed or can be significantly affected by any reasonable process. We also have direct observation:


That radiocarbon ages agree so closely with tree-ring counts over at least 8000 years, when the observed magnetic effect upon the production rate of C-14 is taken into account, suggests that the decay constant itself can be assumed to be reliable.


(Strahler, 1987, p.157)


Since 8000 years is almost two half-lives for carbon-14, it's half-life being 5730 years (plus or minus 40 years), we have excellent observational evidence that the decay rate is constant. We also have laboratory studies which support the constancy of all the decay rates used in radiometric dating.


A great many experiments have been done in attempts to change radioactive decay rates, but these experiments have invariably failed to produce any significant changes. It has been found, for example, that decay constants are the same at a temperature of 2000 degrees C or at a temperature of -186 degrees C and are the same in a vacuum or under a pressure of several thousand atmospheres. Measurements of decay rates under differing gravitational and magnetic fields also have yielded negative results. Although changes in alpha and beta decay rates are theoretically possible, theory also predicts that such changes would be very small [Emery, 1972] and thus would not affect dating methods. Under certain environmental conditions, the decay characteristics of C-14, (cobalt-60) Co-60, and (cerium-137) Ce-137, all of which decay by beta emission, do deviate slightly from the ideal random distribution predicted by current theory [ Anderson, 1972; Anderson & Spangler, 1973], but changes in the decay constants have not been detected.


There is a fourth type of decay that can be affected by physical and chemical conditions, though only very slightly. This type of decay is electron capture (e.c. or K-capture), in which an orbital electron is captured by the nucleus and a proton is converted into a neutron. Because this type of decay involves a particle outside the nucleus, the decay rate may be affected by variations in the electron density near the nucleus of the atom. For example, the decay constant of (beryllium-7) Be-7 in different beryllium chemical compounds varies by as much as 0.18 percent [Emery, 1972, 64]. The only isotope of geologic interest that undergoes e.c. decay is (potassium-40) K-40, which is the parent isotope in the (potassium-argon) K-Ar method. Measurements of the decay rate of K-40 in different substances under various conditions indicate that variations in the chemical and physical environment have no detectable effect on its e.c. decay constant.


(Dalrymple, 1984, p.88)


Believe it or not, a number of creationist attacks against radiometric decay rates are aimed at a kind of "decay" called internal conversion (IC), which has absolutely nothing to do with the radiometric dating methods (Dalrymple, 1984, p.88). Harold Slusher, a prominent member of the Institute for Creation Research, claimed that "Experiments have shown that the decay rates of cesium 133 and iron 57 vary, hence there may be similar variations in other radioactive decay rates." (Slusher, 1981, p.22, 49; from Brush)


These are both stable isotopes so there is no decay rate to be changed. This statement merely reveals Slusher's ignorance of nuclear physics. (Gamma decay of an excited state of iron 57 has been studied, but this has nothing to do with the kinds of decays used in radiometric dating.)


(Brush, 1982, p.52)


DeYoung [1976] lists 20 isotopes whose decay rates have been changed by environmental conditions, alluding to the possible significance of these changes to geochronology, but the only significant changes are for isotopes that "decay" by internal conversion. These changes are irrelevant to radiometric dating methods.


(Dalrymple, 1984, p.88)


Keep an eye on those creationists! They will switch tracks faster than you can say "tiddlywinks." One moment they're talking about the radioactive decay of the nuclides involved in geochronology, and, in the next moment, they're passing out examples of IC decay in stable isotopes. Morris (1974) claimed that free neutrons might change the decay rates. However, Henry Morris, that icon of creationism, only demonstrated that he knew no more about radiometric dating than does Dr. Hovind today. "...[Morris'] arguments show that he does not understand either neutron reactions or radioactive decay." (Dalrymple, 1984, pp.88-89). Free neutrons might change one element into another, but the decay rates all remain true to their elements.


Another attempt by Morris invokes neutrinos.


Morris [1974] also suggests that neutrinos might change decay rates, citing a column by Jueneman (72) in Industrial Research. The subtitle of Jueneman's columns, which appear regularly, is, appropriately, "Scientific Speculation." He speculates that neutrinos released in a supernova explosion might have "reset" all the radiometric clocks. Jueneman describes a highly speculative hypothesis that would account for radioactive decay by interaction with neutrinos rather than by spontaneous decay, and he notes that an event that temporarily increased the neutrino flux might "reset" the clocks. Jueneman, however, does not propose that decay rates would be changed, nor does he state how the clocks would be reset; in addition, there is no evidence to support his speculation.


(Dalrymple, 1984, p.89)


There was also an attempt by Slusher and Rybka to invoke neutrinos. Those mysterious neutrinos seem to be a hot topic!


Slusher (117) and Rybka (110) also propose that neutrinos can change decay rates, citing an hypothesis by Dudley (40) that decay is triggered by neutrinos in a "neutrino sea" and that changes in the neutrino flux might affect decay rates. This argument has been refuted by Brush (20), who points out that Dudley's hypothesis not only requires rejection of both relativity and quantum mechanics, two of the most spectacularly successful theories in modern science, but is disproved by recent experiments. Dudley himself rejects the conclusions drawn from his hypothesis by Slusher (117) and Rybka (110), noting that the observed changes in decay rates are insufficient to change the age of the Earth by more than a few percent (Dudley, personal communication, 1981, quoted in 20, p.51). Thus, even if Slusher and Rybka were correct--which they are not--the measured age of the Earth would still exceed 4 billion years.


(Dalrymple, 1984, p.89)


Dalrymple goes on to debunk several other creationists attacks on the reliability of the radiometric decay rates used in geochronology. Judging from the above, it is easy to see that creationists are indulging in wild fishing expeditions. Compare their flighty arguments to the solid support provided by theoretical work, laboratory testing, and, for the shorter half-lives, actual observation, and add to that the statistical consistency of the dates obtained, including numerous cross-checks between different "clocks," and only one conclusion is left. The radiometric decay rates used in dating are totally reliable. They are one of the safest bets in all of science.

Carbon-14 Decay Rate

How Good Are Those Young-Earth Arguments?
A Close Look at Dr. Hovind's List of Young-Earth Arguments and Other Claims
by Dave E. Matson
Copyright © 1994-2002


The following material has been taken from a sheet entitled Several Faulty Assumptions Are Used in all Radiometric Dating Methods. Carbon 14 is used for this example:, which was put out by Dr. Hovind.


Dr. Hovind (R1): The atmospheric (Carbon-14) C-14 is presently only 1/3 of the way to an equilibrium value which will be reached in 30,000 years. This nullifies the carbon-14 method as well as demonstrating that the earth is less than 10,000 years old.

The above is offered as a simple fact of research. Knowing how faulty creationist "facts" can be, let's do a little research of our own. One suspects that the scientific world would not be using the carbon-14 method if it were so obviously flawed. Could it be that the whole scientific community has missed this point, or is it another case of creationist daydreaming?


This argument was popularized by Henry Morris (1974, p.164), who used some calculations done in 1968 by Melvin Cook to get the 10,000-year figure. In 1968 another creationist, Robert L. Whitelaw, using a greater ratio of carbon-14 production to decay, concluded that only 5000 years passed since carbon-14 started forming in the atmosphere!


The argument may be compared to filling a barrel which has numerous small holes in its sides. We stick the garden hose in and turn it on full blast. The water coming out of the hose is analogous to the continuous production of carbon-14 atoms in the upper atmosphere. The barrel represents the earth's atmosphere in which the carbon-14 accumulates. The water leaking out the sides of the barrel represents the loss (mainly by radioactive decay) of the atmosphere's supply of carbon-14. Now, the fuller that barrel gets the more water is going to leak out the thoroughly perforated sides, just as more carbon-14 will decay if you have more of it around. Finally, when the water reaches a certain level in the barrel, the amount of water going into the barrel is equal to the amount leaking out the perforated sides. We say that the input and output of water is in equilibrium. The water level just sits there even though the hose is going full blast. (The barrel is made deep enough so that we don't have to worry about water overflowing the rim.)


Henry Morris argued that if we started filling up our empty barrel it would take 30,000 years to reach the equilibrium point. Thus, he concluded, if our Earth were older than 30,000 years the incoming water should just equal the water leaking out. That is, the equilibrium point should have long since been reached given the present rate of carbon-14 production and the old age of the earth. The next step in Henry Morris' argument was to show that the water level in our barrel analogy was not in equilibrium, that considerably more water was coming in than leaking out. To that end, he quoted some authorities, including Richard Lingenfelter. Having accomplished that, Morris concluded that the barrel was still in the process of being filled up and that, given the present rate of water coming in and leaking out, the filling process began only 10,000 years ago.


It's a great argument except for one, little thing. The water is not coming out of the hose at a steady rate as our model assumed! Sometimes it slows down to a trickle so that much more water is leaking out the barrel than is coming in; sometimes it goes full blast so that a lot more water is coming into the barrel than is leaking out. Thus, the mere fact that the present rate of water coming in exceeds that of the water leaking out cannot be extrapolated back to a starting time. And, that destroys the entire argument. (See Figure 1).


'The water in the barrel represents the c-14 in the atmosphere. The water coming in represents c-14 being added to the atmosphere. The leaking water represents the decay of the carbon-14. If the inflow is steady, and if equilibrium hasn't been reached, and exceptional water bug in the barrel could calculate how long the process has been going on.'

Water barrel analogy for carbon-14 in the atmosphere

Figure 1


Lingenfelter's paper was written in 1963, before the cycles of C-14 variation we described had been fully documented. The point is that fluctuations in the rate of C-14 production mean that at times the production rate will exceed the decay rate, while at other times the decay rate will be the larger.


(Strahler, 1987, p.158)


Lingenfelter actually attributed the discrepancy between the production and decay rates to possible variations in the earth's magnetic field, a conclusion which would have ruined Morris's argument. Henry Morris chose not to mention that portion of the paper! Creationists don't want their readers to be distracted with problems like that -- unless the cat is already out of the bag and something has to be said.


Tree-ring dating (see Topic 27) gives us a wonderful check on the radiocarbon dating method for the last 8000 years. That is, we can use carbon-14 dating on a given tree-ring (the 8000-year sequence having been assembled from the overlapping tree-ring patterns of living and dead trees) and compare the resulting age with the tree-ring date. A study of the deviations from the accurate tree-ring dating sequence shows that the earth's magnetic field has an important effect on carbon-14 production. When the dipole moment is strong, carbon-14 production is suppressed below normal; when it is weak, carbon-14 production is boosted above normal. What the magnetic field does is to partially shield the earth from cosmic rays which produce carbon-14 high in the atmosphere.


Contrary to creationist Barnes' totally discredited claims, which I've covered in Topic 11, the earth's magnetic field (dipole moment) has, indeed, increased and decreased over time. Strahler presents a graph of the earth's dipole moment going back 9000 years.


Figure 19.5, curve C, shows the dipole field strength calculated from measurements of magnetism of lava flows and of artifacts such as pottery and bricks, whose age can be determined. The curve is roughly fitted to mean values determined about every 500 to 1,000 years... The curve is roughly 180 degrees out of phase with the C-14 curve.


(Strahler, 1987, p.156)


The idea [that the fluctuating magnetic field affects influx of cosmic rays, which in turn affects C-14 formation rates] has been taken up by the Czech geophysicist, V. Bucha, who has been able to determine, using samples of baked clay from archeological sites, what the intensity of the earth's magnetic field was at the time in question. Even before the tree-ring calibration data were available to them, he and the archeologist, Evzen Neustupny, were able to suggest how much this would affect the radiocarbon dates. (Renfrew, p.76)


(Weber, 1982, p.27)


Thus, at least within the last 9000 years, the earth's magnetic field has fluctuated and those fluctuations have induced fluctuations in the production of carbon-14 to a noticeable extent. Therefore, as already noted, Dr. Hovind's claim that carbon-14 has been slowly building up towards a 30,000 year equilibrium is worthless. You now have the technical reason for the failure of Morris' model.


It may interest the reader to know that within this 9000-year period, where the radiocarbon method can be checked by tree-ring data, objects older than 400 BC receive a carbon-14 date which makes them appear younger than they really are! An uncorrected carbon-14 date of 6000 years for an object would actually mean that the object was 6700 years old. Seven hundred years or so is about as far as the carbon-14 method strays from tree-ring dating on the average. Individual dates given on a 1973 correlation chart (Bailey, 1989, p.100) show that objects with true ages between 4200 BC and 5400 BC would receive a carbon-14 date making them appear 500-900 years too young. As it turns out, we have a check on the carbon-14 production which goes back even further than 8000 years:


Evidence of past history of C-14 concentration in the atmosphere is now available through the past 22,000 years, using ages of lake sediments in which organic carbon compounds are preserved. Reporting before a 1976 conference on past climates, Professor Minze Stuiver of the University of Washington found that magnetic ages of the lake sediments remained within 500 years of the radiocarbon ages throughout the entire period. He reported that the concentration of C-14 in the atmosphere during that long interval did not vary by more than 10 percent (Stuiver, 1976, p. 835).


Thus, the available evidence is sufficient to validate the radiocarbon method of age determination with an error of about 10 percent for twice as long a period as the creation scenario calls for.


(Strahler, 1987, p.157)


Yes, the atmospheric content of carbon-14 can vary somewhat. The dipole moment of the earth's magnetic field, sunspot activity, the Suess effect, possible nearby supernova explosions, and even ocean absorption can have some effect on the carbon-14 concentration. However, these factors don't affect the radiocarbon dates by more than about 10-15 percent, judging from the above studies. Of course, when we reach the upper limit of the method, around 40,000 years for the standard techniques, we should allow for much greater uncertainty as the small amounts of C-14 remaining are much harder to measure.


Tree-ring data gives us a precise correction table for carbon-14 dates as far back as 8,000-9,000 years. The above study by Stuiver shows that the C-14 fluctuations in the atmosphere were quite reasonable as far back as 22,000 years ago. The earth's magnetic field seems to have the greatest effect on C-14 production, and there is no reason to believe that its strength was greatly different even 40,000 years ago. (For a refutation of Barnes' argument see Topic 11.)


Therefore, atmospheric variation in C-14 production is not a serious problem for the carbon-14 method. The evidence refutes Dr. Hovind's claim that the C-14 content of our atmosphere is in the middle of a 30,000-year buildup. Thus, we can dismiss this young-earth argument.
