Matt Young Not Happy With Treatment of Andrew Snelling

Neither am I.  It seems that Andrew Snelling, a young earth creationist, wanted to do a geological study of rocks in the Grand Canyon and so petitioned the National Park Service to remove a few rocks to do this.  After reviewing the proposal that Snelling sent, the Park Service declined.  Citing religious descrimination, Snelling is suing the Park Service.  Here is an excerpt from the story in the Phoenix New Times:
In the federal complaint filed on Tuesday, ADF uses several key e-mails by scientists who put their feelings in writing to demonstrate the bias Snelling says he encountered.

"It is difficult to review such an outlandish proposal," Ron Blakely of Northern Arizona University told NPS officials in 2014, when he was asked for his opinion about Snelling's proposal.

Gary McCaleb, ADF senior counsel, told Phoenix New Times that Snelling "has been stonewalled for three years. Something's fundamentally wrong when a government stops a good scientist from doing good research."

Whether it's actually "good" research is debatable, of course. But it's unclear why government officials care what Snelling concludes about a relatively small collection of Grand Canyon rocks.
Here is Matt Young's take on it, from Panda's Thumb:
I do not know how many people request permission to remove a few rocks from the Grand Canyon. But Dr. Snelling’s proposal was to remove no more than 60, ~0.2 kg samples to use in his research. He did not ask for any funding. There is not the slightest doubt that his research would conclude that the Grand Canyon was something like 6000 years old. That is, he is pursuing, in the jargon of the times, fake research. So what? It would have been better if the National Park had allowed him to have his rocks and go play in his sandbox.

Instead, Dr. Snelling is now being represented by the Alliance Defending Freedom, which has just posted an article Grand Canyon National Park continues history of hostility toward religion, and may become something of a cause célèbre among the right wing. The complaint, incidentally, refers irrelevantly to Donald Trump’s recent Executive Order on “religious freedom.”
This kind of thing gives ammunition to the young earth creationists and it was completely unavoidable. The story in Phoenix New Times suggests that reviewer Karl Karlstrom criticized Snelling's beliefs in a letter he sent to the Park Service in 2014.  Without that letter, it is hard to evaluate that charge.  It may be simply that he thought that Snelling's interpretation of the scriptures had no empirical support (which it doesn't).  That is not the same as criticizing his religious beliefs.  On the other hand, if he did criticize Snelling's beliefs, it will be much easier to get a charge of religious bias to stick.

David MacMillan Responds to Todd Wood

David MacMillan, writing at Panda's Thumb, responds to Todd Wood regarding the issue of peer-review of creationist literature.  He writes:
Wood also stated that both the articles I referenced in my original post were, in fact, letters to the editor rather than full refereed journal articles, and thus it isn’t irregular to publish them simultaneously. Here’s where it gets a bit dicey, not because I doubt his explanation, but because ARJ’s editor, Andrew Snelling, apparently made no effort whatsoever to distinguish between letters to the editor and actual articles. That’s a problem.
The whole point of peer review is that it identifies scholarship which has been evaluated by peers. Scientists and researchers learn to trust peer review because they know it has been read and examined with a critical eye, both for careless errors and for systematic errors. Peer review is the dam which holds back the flood of pseudoscientific nonsense (although this doesn’t prevent creationists from trying their damnedest to slip things in). Creationist publications like the Answers Research Journal are creationism’s way of claiming legitimacy.
That’s not to say that individual creationists who submit to publications like ARJ are insincere. Nor are their submissions useless; in many cases, as in the debate over H. naledi, the breadth of discussion illustrates very well the earnest attempt to make their models work. Creationist organizations now make a practice of referring to their “professional, peer-reviewed technical journal(s)” and claiming that “evolutionists are unaware of our scientific literature”. It is because the models do not, in fact, work that we have an opportunity to use their own work against them, highlighting clearly where the different models proposed by different authors are plainly incompatible. Creationists are trying to fit a 4-billion-year-old peg into a 6-thousand-year-old hole, and it shows.
Perhaps the best example of this that I have read in recent memory is the work of Phil Senter, in using flood geologists to invalidate their own models.Young earth creationists want to have their research taken seriously, but since none of their models hold up under scrutiny, and they seem to spend the vast majority of their time trying to poke holes in established science, this has not been forthcoming from the science establishment.  I also question Todd Wood's assertion that scientists are not aware of creationist research.  There are people that do nothing but read what comes out of AiG, CMI and the ICR with an eye for critical science.  Even the work that comes out of the Discovery Institute is put under a microscope.

Snelling should have been absolutely up front about the fact that the responses were letters to the editor.  MacMillan makes the point that the failure to distinguish this smacks of being arbitrary.  More to the point, it allows unvetted opinions and statements to creep in without proper backstopping.  As noted in my previous post, however, my experience is that this has never stopped many young-earth creationists before.

Elizabeth Mitchell, David Menton and Andrew Snelling Take on the Ledi Jaw

As noted, the promised report from Answers in Genesis about the Ledi jaw (LD 350-1) is out.  Let's see what they say.  This is an interesting group of authors.  Andrew Snelling is the resident geologist, while David Menton is a former anatomist who wrote a truly terrible article on the evidence for human evolution, which I tackled over six long, straggly posts, ending here.  In it he, effectively, revealed that he has little to no knowledge of the fossil record.  I have read little of Elizabeth Mitchell's posts, other than the one in which she championed the evidence for unicorns in the Bible. 

The opening salvo in the “Lucy Connection” contains this:
An extinct knuckle-walking ape, “Lucy” is generally depicted strolling about East Africa 3 million years ago on her two supposedly arched feet with tiny teeth smiling from her gorilla-like face and tiny brain. That image has created an imaginary place for Australopithecus afarensis in the human lineage.
The initial problem with this paragraph is that there is no evidence to back up their depiction of Au. afarensis. The fossil remains that make up Au. afarensis, of which Lucy is a member, clearly indicate a hominin that was bipedal; that much is not debatable.  It carries none of the traits of an ape in this regard.  However, Au. afarensis does have some ape-like characteristics as well.  In fact, there are quite a list of traits that are Hominin and some that are ape-like.  I chronicled those here, in the fourth part of my response to Menton's 2010 article on human origins.  (Aside: It doesn't bother me that Menton didn't read my post, although Ken Ham knows I write for BioLogos because he referenced one of my posts for them.  It does bother me that Menton persistently mischaracterizes the transitional evidence in Au. afarensis, which is pretty hard to miss, if you are paying any attentional, whatsoever.)

Now, on to the jaw, itself, for which they get the account correct (Here is my short post for BioLogos on the jaw).  In fact, they report pretty much exactly what the discoverers and Fred Spoor determined about the jaw and the reconstruction of the related OH 7 skull. 

The the wheels fall off.

They write:
Could the Ledi jaw’s owner have been a transitional form? No. Evolutionists strain to see something ape-like in the array of Homo traits in the Ledi jaw because its position in the fossil record is so “far back” they think it must be their much sought-after transitional form. Since it lacks a protruding chin no one would suggest this fossil belonged to a modern human, but the lack thereof does not demonstrate that it is Australopithecus afarensis or an ape descended from it or even a less-evolved part of the human lineage. The relatively chinless jaw is simply not typical of modern humans. Nothing about this fossil indicates that its owner still had one foot in the ape-camp and was only in the process of evolving into a full-fledged human.
They are correct that the lack of a chin keeps it out of the modern human camp.  They are incorrect that it doesn't have transitional characteristics. Here is the relevant quote from the article1:
Indeed, in overall dental and mandibular size LD 350-1 matches smaller specimens of A. afarensis (figs. S1 to S4 and tables S1 to S3). In addition, LD 350-1 shares with A. afarensis a primitive anterior corpus, including an inclined symphyseal cross section, a bulbous anterior symphyseal face, and a projecting inferior transverse torus that is only slightly elevated above the corpus base (Fig. 2A).
What then follows in the scholarly article is a long discussion of no fewer than five distinct characteristics that align the Ledi jaw with Homo to the exclusion of Au. afarensis.  Villmoare and colleagues are keenly aware of the differences between australopithecine and human morphology.  This is why they can recognize these traits.  Thus, when Mitchell, Menton and Snelling write that nothing about the Ledi Jaw is transitional, and provide no evidence of their position, one is tempted to not take them seriously.  The next paragraph is no better:
The Ledi jaw’s bid to be Homo or an early transition to Homo rests largely on the fact that its assigned dates place it in the desired gap between the ape Lucy and archaic varieties of humans. Had its host sediment been dated substantially older, its human features would likely have been ignored or explained away. Evolutionists have been known to dismiss fossil evidence of very early Homo, no matter how similar to modern man, if the stratigraphically assigned dates are too old to fit into the evolutionary schema.
This is illogical. Why would evolutionists care how old it is? There are some, in fact, who would relish the idea of our line being pushed back even further.  The human features are there, regardless of how old it is.  That is why it is making waves—because it has the human features.  If it had been found to be older, the human-like features would not have vanished like the snows of yesteryear.  They would still have been there. 

The last sentence in the quote is, once again, presented without evidence and calls into question the integrity of the scientists involved in this discovery and others like it.  What evidence has been dismissed?  How has it been explained away? To call into question the motives of scientists and call them duplicitous without giving evidence to that effect is worthy of scorn and disrespect.  Put up or shut up.

Next.
The Ledi jaw wouldn’t even be close to being the oldest “Homo” if certain other fossil bones and footprints that are virtually identical to modern man were rightly recognized as Homo sapiens. For example, the Laetoli footprints are claimed to be 3.66 million years old and are virtually identical to modern man’s footprints, but no evolutionist considers them to be human because they are simply too old. The Kanapoi elbow fossil from the Lake Rudolf region of northern Kenya is the distal end of a humerus that is indistinguishable from Homo sapiens, but it is considered to be australopithecine in origin because it is also too old at 4.0–4.5 million years to be considered human. These assigned dates, based on a host of worldview-based unverifiable assumptions, blind evolutionists to the true identity of fossils like these. In truth, humans have been around since the sixth day of the Creation Week, the first two people having been created by God the same day as the land animals.
They are right, the footprints are too old, given that there is no evidence for modern humans until around 190 thousand years ago. The footprints are securely dated by radiometric techniques that the folks from AiG will never accept, despite their robusticity.  Same with the Kanopoi remains.  What this simply means is that, as with many transitional forms at this time, some characteristics were more human-like than others.  What these authors do not mention is that in other fossils from the time period, there are ape-like characteristics as well.  The elbow traits, along with the knee and hip traits are derived in the direction of Homo.  The simian traits are retained from their ancestors.

What these authors do fail to demonstrate is that there are fully modern humans in the same strata as the australopithecines.  That would sink our understanding of human origins once and for all.  Yet, that has never been done. 

They write that this fossil is dated using methods found to have “unverifiable assumptions.”  Curiously, this links to another AiG page on radiometric dating, which, in turn, links to an article authored by Steve Austin, of the ICR, on radiometric dating of Mount St. Helens, rather than actual peer-reviewed scientific articles.

Austin collected dacite samples from around the new St. Helens lava dome, which he knew had been formed around 1986.  He then separated them and sent them to a laboratory for potassium/argon dating.  When the results came back, he declared that radiometric dating was flawed because the results inticated that the dome had been formed around 350 000 years B.P.

In Kevin Henke's response to this report, he addresses how Austin misused the methodology to arrive at his conclusions.  He writes:
Considering that the half-life of potassium-40 (40K) is fairly long (1,250 million years, McDougall and Harrison, 1999, p. 9), the K-Ar method cannot be used to date samples that are much younger than 6,000 years old (Dalrymple, 1991, p. 93). A few thousand years are not enough time for 40Ar to accumulate in a sample at high enough concentrations to be detected and quantified. Furthermore, many geochronology laboratories do not have the expensive state-of-the-art equipment to accurately measure argon in samples that are only a few million years old. Specifically, the laboratory personnel that performed the K-Ar dating for Austin et al. Specifically, personnel at Geochron Laboratories of Cambridge, Massachusetts, USA, performed the K-Ar dating for Austin et al. This laboratory no longer performs K-Ar dating. However, when they did, their website clearly stated in a footnote that their equipment could not accurately date rocks that are younger than about 2 million years old ("We cannot analyze samples expected to be younger than 2 M.Y."; also see discussions by Bartelt et al.). With less advanced equipment, 'memory effects' can be a problem with very young samples (Dalrymple, 1969, p. 48). That is, very tiny amounts of argon contaminants from previous analyses may remain within the equipment, which precludes accurate dates for very young samples. For older samples, which contain more 40Ar, the contamination is diluted and has insignificant effects. Considering the statements at the Geochron website and the lowest age limitations of the K-Ar method, why did Austin submit a recently erupted dacite to this laboratory and expect a reliable answer??? Contrary to Swenson's uninformed claim that ' Dr Austin carefully designed the research to counter all possible objections', Austin clearly demonstrated his inexperience in geochronology when he wasted a lot of money using the K-Ar method on the wrong type of samples.
lawilson200 of Mount St. Helens watch also notes these problems, as does Skeptoid.  If Austin sent the samples to the lab that he knew were produced in 1986, then he either did not know that K/Ar dating requires samples that are at least two million years old to date accurately, or he did know that and submitted them to intentionally get spurious results to publicize the perceived limitations of radiometric dating.  In any event, without the support of Austin's argument, the bad date argument for the Ledi jaw collapses. 

Mitchell, Menton and Snelling write that the geologists studying the area around where the Ledi jaw was found cannot be sure how many stratigraphic layers are missing between the Gurumaha tuff beds and the Lee Adoyta tuff beds, so we cannot know for sure what the total thickness was.  Yes, but we know where the jaw was found and the authors are clear about what the maximum and minimum ages for the fossil can be, based on the dates.  The AiG writers then make an argument that the tuffs could have been formed in hours because of the nature of volcanic eruptions.  This fails to account for the depositional environment between the tuffs, to wit:
Ecological community structure analysis based on mammalian fauna recovered from the Gurumaha fault block indicates a more open habitat (mostly mixed grass-lands/shrublands with gallery forest) that likely experienced less rainfall than any of those reconstructed for the Members of the Hadar Formation (6). The landscape was similar to modern African open habitats, such as the Serengeti Plains, Kalahari, and other African open grasslands, given the abundance of grazing species and lack of arboreal taxa, although the presence of Deinotherium bozasi and tragelphins likely indicate a gallery forest (fig. S6). The existence of Kobus sigmoidalis, aff. Hippopotamus afarensis, crocodiles, and fish in this package reflect the presence of rivers and/or lakes. Approximately one-third of the mammalian taxa present are shared with the youngest Hadar Formation (~3 Ma), while one-third are first appearances of these taxa in the LAV (Table 1). The remaining one-third of mammals recovered can only be identified to the genus level.
How would these landscapes have formed in hours? They reflect hundreds, if not thousands of years of development, and they certainly could not have formed in the middle of a world-wide flood.

The argument presented by AiG also points to a peculiarity of the young earth argument: arguing against a proposition using uniformitarian principles, while at the same time taking no stock in those principles, whatsoever, since they have to be thrown out the window in any flood model. 

They continue:
The evolutionary determination to subdivide varieties of humans into various species is based on evolutionary claims, when in reality all humans would best be called Homo sapiens regardless of their variations. Nevertheless, we are stuck with the terminology that calls the descendants of various people descended like us from Adam and from Noah via the dispersion from Babel by names that imply they are unrelated. Truly, however, when it comes to a fossil like this one, the real question should not be “where in the evolutionary history of humans does it fit?” but rather “does it fit within the norms for human beings or not?” Though limited by its incompleteness, analysis of LD 350-1 suggests it belonged to a person.
Once again, how, then, do you explain the traits that link it to Au. afarensis? Those are clearly non-human. To sweep them under the rug is simply not tenable. These traits are outside the known variation of all modern humans.  No one has them.  Further, they don't even track with traits seen in later hominin forms such as Homo ergaster, Homo erectus or archaic Homo sapiens.  They are clearly australopithecine.

In summary, then, this article written by Mitchell, Menton and Snelling suffers from three principle problems:
  1. A failure to correctly describe the fossil material related to the Ledi jaw (Describing Au. afarensis as “An extinct knuckle-walking ape,” for example)
  2. A failure to correctly assess the human and non-human morphology of the Ledi jaw, itself, instead simply denying that the non-human traits exist, when in fact, they clearly link it to the preceding australopithecine fossil remains in many ways.
  3. Reliance on a single article for rejection of modern radiometric dating assumptions that has been heavily criticized for its misuse of proper methodology. (See this Davis Young article on radiometric dating for a good primer on how reliable it is).
These problems completely sink the AiG's analysis and conclusions of the Ledi jaw.

Ken Ham, Andrew Snelling, Creationism and the Challenge of Modern Geology

Recently, a story showed up in the science dailies about evidence supporting rapid canyon formation in Iceland.  First, the story that the BBC ran:
The Jokulsargljufur canyon, 28km long and up to 100m deep, is home to Europe's most powerful waterfall. By analysing the chemistry of rocks in the canyon's walls, the researchers constructed a timeline of how the canyon was shaped over time. Most changes seem to have taken place during three brief but brutal periods. Interestingly, these key flooding events occurred two, five and nine thousand years ago - separated by millennia of relative stability. Writing in the journal Proceedings of the National Academy of Sciences (PNAS), the scientists say their findings demonstrate the importance of brief but cataclysmic events in shaping landscapes.
What the story goes on to say is that each brief, but brutal period may have been a matter of days.  This is fascinating but is not unique.  A similar even occurred in eastern Washington State in the late Pleistocene when there were a series of massive floods that carved out huge areas, creating the scablands.  Consequently, while this report is interesting, there is clearly a precedent for rapid movement of sediment by fast-moving water. Another example of this is the Canyon Lake Gorge, in Texas, which was formed in one very large flood, in 2002. 

Fast, torrential floods carving huge canyons quickly out of solid rock. This was too much of an opportunity for Ken Ham to pass up. Very shortly, his post titled Secularists Say Landscapes Can Form in Days came out. (Aside: note the title.  Ham has dispensed with all pretenses of being inclusive, now considering anyone who supports an old earth and the standard geological model a “secularist.”  There can be no room in Bible-believing Christian circles for those not espousing the young earth view.  Organizations like the Association of Christian Geologists are dismissed out of hand.) Ham writes:
Researchers studying Europe’s most powerful waterfall and the canyon containing it reportedly reached the conclusion that they were “created in a matter of days by extreme flooding.” Rather than being the result of slow-and-gradual processes, these researchers believe that a series of extreme floods several thousand years apart formed the waterfall and the canyon catastrophically. They say that these “findings demonstrate the long-term impact that extreme flood events can have on landscapes.”

The leader of the study apparently stated, “We think of natural environments as being formed over thousands of years, but sometimes they are shaped very suddenly. This insight into one of Iceland’s magnificent landscapes helps us better understand these processes, and illustrates their legacy.”

Of course, we have already known that because the Bible tells us that we live on a young Earth. Geological features cannot take millions of years to form slowly and gradually because the planet isn’t that old! When we start with the Bible we know that we live on a young Earth that was radically reshaped by a massive catastrophe, the global Flood. The Flood and its aftermath explain many of the geologic features we see today.
First, it is intellectually dishonest to accept only the sections of someone's argument that you agree with and dispense with the rest.  This is, charitably, cherry-picking the data.  Ham is quite willing to agree that the Jokulsargljufur canyon was formed very quickly, but not that it represents several episodes thousands of years apart.

Ham then calls on Andrew Snelling, the resident geologist, who figured into my last post. In response to the story, Snelling writes:
This is a brief reminder that even uniformitarians are finding that the actual observational data can only explain the formation of landforms such as canyons and massive waterfalls by catastrophic floods, not the present-day slow-and-gradual geologic processes. Of course we disagree on the timescale, but agree this canyon and waterfall in Iceland were carved after the Ice Age, the one short Ice Age that occurred after the Genesis Flood. And rather than floods being thousands of years apart, they would have been only years to decades apart. Of course, this canyon formed in hardened basalt layers in contrast to the soften volcanic ash layers at Mount St. Helens, but it still resulted from catastrophic floods which carved through the solid rock as though it were soft!
Uniformatarians aren't finding anything of the sort. Snelling is clearly putting up a straw man argument by claiming that geologists conclude that canyons can only form rapidly.  There are quite a few canyons around the world that show evidence of having been formed over quite a long period of time and geologists know it. Even the geologically recent Grand Canyon has likely been forming over the last six million years. By the way, for scale purposes, the Jokulsargljufur Canyon is 300 feet deep. the Grand Canyon, which would have to have been formed in the same, rapid fashion, is, from the top of the north rim to the canyon floor, 5500 feet, or over eighteen times as deep as the Jokulsargljufur Canyon.  Its only known water source is the Colorado River. 

But the logical errors continue.  In order for their world-wide flood model to work, flood geologists must use the “part to whole” fallacy.  In other words, what is happening at the Jokulsargljufur canyon would have to be happening all over the world.  Not just canyon formation but all rock formation, everywhere.  While it is quite possible that, in some instances, magmatic rock can form quickly, its formation is very easy to spot because it is very distinctive.  But it is the only kind of rock that can form quickly.  Metamorphic and sedimentary rock, which are also quite distinctive in their appearance, take considerably longer to form.   Further, it is estimated that up to 70% of the planet's stratigraphic rock formations are sedimentary, in origin and these formation leave extensive layering.  These rocks form by means of wind, water action, glacial action and other slow processes.  They do not form quickly.  Metamorphic rock forms even more slowly than sedimentary rock because it can only form under considerable heat and pressure.  In the context of a world-wide flood, how would these rocks, which require heating to between 150° and 200°, have formed in the first place? Ham and Snelling are suggesting, in this model, that the geological column settled, hardened into rock by an as-yet undetermined very rapid heating process, and Then incised the canyon over the still-hardening rock.  They provide no explanation for how this would happen.

It is disappointing to see that, in their zeal to disregard the work of mainstream geologists and brand them all as “secularists,” a term that is surely pejorative in this context, they present arguments that fail to stand up to even rudimentary scrutiny.  This is part and parcel of young earth creationism and this example represents only a microcosm of the insurmountable problems that it faces.  It is almost as if they feel that their devotion to their understanding of scripture should be enough to sway the reader into supporting the young earth model...just don't look too closely.

Andrew Snelling, Geology and Cooking

Sorry, this one rambles a little bit.

Jonathan Baker at Age of Rocks writes an interesting column that is a response to Andrew Snelling's preposterous statement that one can be a successful petroleum geologist and yet be a young earth creationist.  In his column, he likens the different layers of the rock record to the baking of a cake.  After a series of trials in which a cake is cooked for thirty minutes at 150º, then 350º, then 500º, he writes:
In the first trial, it seems, the batter never reached a high enough temperature for these reactions to complete; in the third trial, there were too many! Thus we all know from experience that the results of our cooking depend strongly on the chosen temperature and time. Consider also the various ways to make a roast: we can cook the meat for a short time at high temperature, for a long time at low temperature, or choose some option in between. Why? Because the rate of chemical reactions is temperature dependent, and for every ~10°C increase in temperature, the reaction rate doubles.
Why is this important to understanding the rock record and petroleum geology? He continues:
This flexibility in cooking reflects a basic principle in petroleum geology called the Time-Temperature Index (TTI). The deposition of organic matter in sedimentary layers is much like pouring a raw cake batter into a pan. As those sediments are buried deeper, the temperature naturally increases, due to what’s called the geothermal gradient (heat flows from the Earth’s center to its surface, so temperature increases with depth). Once the temperature becomes high enough, those same chemical reactions that turned our batter into cake can also turn raw organic matter into a suite of energy-rich hydrocarbons (oil and gas). But the actual cooking time depends on the absolute temperature to which those molecules are exposed.

In other words, the Earth’s subsurface works like a giant oven—in fact, this terminology is frequently used by petroleum geologists. As with cooking in our homes, the end result depends on three factors: the original recipe, time, and temperature. When geologists search for oil/gas, they try to constrain those variables as best they can.
The upshot is that, due to the nature of the geothermal gradient, there simply has not been enough time to produce oil if the earth is only six thousand years old. Further, because geologists use this gradient to their advantage in examining the geological column, they have become very good at finding oil.

One of the grand daddies of modern young earth creationism, George McReady Price, received a letter from Harold Clark, another Seventh Day Adventist and fellow creationist, when Clark went out to visit the oil fields in Texas, in 1938. When he got there, Clark received a bit of a shock.  The letter read in part:
"The rocks do lie in a much more definite sequence than we have ever allowed. The statements made in your book, The New Geology, do not harmonize with the conditions in the field. All over the Midwest the rocks lie in great sheets extending over hundreds of miles, in regular order. Thousands of well cores prove this. In East Texas alone are 25,000 deep wells. Probably well over 100,000 wells in the Midwest give data that has been studied and correlated. The science has become a very exact one. Millions of dollars are spent in drilling, with the paleontological findings of the company geologists taken as the basis for the work. The sequence of the microscopic fossils in the strata is remarkably uniform. The same sequence is found in America, Europe, and anywhere that detailed studies have been made. This oil geology has opened up the depths of the earth in a way that we never dreamed of twenty years ago"
Astoundingly, people like Snelling never seemed to learn from the experience that Clark had.  In the last seventy-seven years, oil and gas explorers haven't adopted any form of young earth creationism in their efforts to find oil.  Instead, they have become better at it by using standard, well-understood modern geological methods and an understanding of the geological column that was well-known even in Clark's time.  To debate this on the part of Snelling is willful blindness. 

In some ways, this is analogous to the problem of what you would find in terms of consistency if the geological column were only 4500 years old and really did reflect the remnants of the world-wide flood.  If you could, the experiment might work like this: construct a tank that was a mile high, fill it with about 1000 feet of dirt (remember, the geological column did not exist at all before the flood but they had to be walking around on something), then pour water into the tank, simulating rain for 365 days.  At the end of that period, let the tank drain away (what the flood waters are said to have done).  You know what you will find at the end of that time?  You will find very hard mud at the bottom, medium hard mud in the middle and soupy mud at the top.  What you will not find is sedimentary rock of any kind.  You won't find sandstones, you won't find shales, you won't find chert and you won't find limestone.  Why?  You won't find them because it takes lots and lots of time for these kinds of rocks to form.

Young earth creationist studies of the Grand Canyon are interesting in this regard.  They fail to account for the fact that the walls of the canyon, had they been formed in a year's time, would not have been solid enough to stand up.  Being mostly mud, they would have collapsed, which is what you typically see in large-scale floods.  In fact, you see the relative hardness of rock on display in the canyon walls: the harder rock walls are more vertical, while the softer rock walls are more eroded.  If it were mud, there would be no canyon at all.

That digressed from the original point but these are just more examples of statements that young earth creationists make that are, on the face of it, absurd.  To paraphrase Conrad Hyers: you are asked to believe several impossible things before breakfast.

Creation Museum To Get Allosaurus Skull

The AP is reporting that the Creation Museum, in Petersburg, Kentucky, has become the recipient of a privately donated, almost complete (but plastically deformed) Allosaurus skull.  Dylan Lovan writes:

The museum said in a written statement Friday that the Allosaurus probably stood about 10 feet tall and 30 feet long, and was a meat-eater. The skeleton, nicknamed "Ebenezer," includes a skull with 53 teeth and will go on display in an exhibit next year.

"For decades I've walked through many leading secular museums, like the Smithsonian in Washington, and have seen their impressive dinosaur skeletons, but they were used for evolution," said Ken Ham, co-founder of the Answers in Genesis ministry, which operates the museum. "Now we have one of that class for our museum."
Unfortunately, they have no idea what to do with it other than put it on display. They can't do a taxonomic study because that would involve evolutionary biology. They cannot try to place it in a geological context because that would involve mainstream geology. All they can really do is sit and look at it.

The story continues:
The well-preserved condition of the Allosaurus is evidence that it died during a worldwide flood as described in the Bible's Old Testament, Andrew Snelling, a geologist at the Creation Museum, said in the statement.

Snelling said the fossil's intact skeleton is proof of an extremely rapid burial, "which is a confirmation of the global catastrophe of a flood a few thousand years ago."
That is absurd. The fact that it was buried rapidly constitutes no evidence whatsoever that it was buried during a world-wide flood. There are plenty of examples of animals that become entombed and fossilized in contexts that didn't involve water.  This happens routinely in volcanic sediments.  The Ashfall deposits in Yellowstone and the Liaoning fossil beds in China are prime examples.    Ironically, it is the deposits at Liaoning that are so damaging to the flood model because they represent multiple volcanic eruptions over  a considerable depositional thickness, something that could not possibly have happened in a world-wide flood. 

The nature of the fossil find, itself, also presents problems for Ham and Snelling (or should, at any rate).  How could something like that fossilize in four and half thousand years?  Actual, carbon-dated archaeological remains that old aren't fossilized.  These, and so many other questions about the flood model are never addressed.

For now, all they can do is put it up and say "Gee, isn't that pretty."
