Ethical Geology?

A comment by "Graydevilcat" on one of my MSH field trip posts brings up an important point:

"In addition, to deny a proposal on the 'possibility' of something coming up is a big step down the slippery slope of guilt by association."

NO!!! GSA has a published, well-known position that creationism is NOT SCIENCE. Austin has a 30 year track record of creationist pseudo-geological research. Guilt by association? Give me a break.

And don't bother me with blather about not infringing on Austin's freedom of speech. GSA is a corporation, not the government, and can bloody well regulate speech as it wishes. Indeed, this is what GSA does every day: it's called "editorial decision-making".

GSA just gave creation "science" its imprimatur and violated its own published position.


While I can't speak for GSA, I can see reasons for rejecting or accepting the MSH field trip proposal. One the one hand, there is the point that "devilcat" brings up - there is no reason, based on past history, that Austin is doing anything but creation flood-geology. And if that is the "paradigm" that Austin is using to inform his statements on the field trip, then that is clearly not science. And my experiences on that trip have only supported that thought. There was no real science on that field trip.

The other point to consider is that, as members of GSA, they are entitled to the opportunity to share ideas (anyone can submit a paper for publication, but it must pass muster before being published). Are field trips subjected to the same level of peer-review as research papers? What if the field trip was proposed by an "Expanding-Earth" proponent? Would their personal feelings about how MSH might inform us about the relative inequities in sea-floor spreading versus subduction render the field trip void? If the earth expansionists laid out a field trip proposal that discussed factual information, and did not advance any particular interpretation, would that field trip be okay?

There was no science brought to the trip by our guides, but the statements made were at least an attempt by the guides to pose their ideas in a non-creationist framework. While it made for weak science, it at least allowed for everyone on the trip to get something constructive from the trip. Did the trip provide some additional "street cred" for flood-geology? Yes, almost certainly. Would denying the trip have opened the door for legal action? Doubtful, since, as "devilcat" said, GSA is not the federal government and does have some editorial control. Would Austin's first-amendment rights have been violated if the trip were cancelled - no, likely not. But, as I understand it, the actual field trip proposal made no mention of creationism or other anti-science goals. And although I do not know the nature of the exchange, I do know that there was an email discussion between Austin and people at GSA.

Ultimately, the trip happened. The benefit to Austin was, at a minimum, a field trip guide publication, at least tacit support for his work by GSA (at least that is how it will be billed), and a training tour for a handful of other creationist flood-geologists. Those of us that do real science got to see a unique section of the debris field, a volcano, some western toads, and we all received a rather nice 60" panoramic photo of the mountain and spirit lake. One more thing that I received was an opportunity to learn about what the young-Earth movement is up to and new ideas on how to teach deep time and evolution in my classes. These classes are taken by education majors, so I end up reaching over a hundred future teachers each year. The better able these students are at discerning real science from cargo-cult science, the better we'll all be.

So that brings me back to my title. Who was being ethical here? Did Austin violate the ethics he's agreed to when he became a member of GSA? Well, from a legal standpoint, I don't think he did as far as the field trip is concerned. Did GSA? Again, from a legal standpoint, I don't think they did when they accepted this field trip proposal. Does the whole thing leave a bad taste in my mouth? Yes, it does. But, the law of unintended consequences can be tricky. I don't think anyone, myself included, would have realized how much science education fodder this trip has provided.

Blogs and Reaching Out to the larger community

One of the things I like about blogs is that it's a quick way to make lots of connections. Sure, there is a lot of chaff, and finding those little kernels of value can take some serious sifting and winnowing, but the internets do have search functions, and it's not like one has to invest a great deal of time in things they don't find interesting.

I've been looking at my visit logs and I've seen a big uptick in activity - largely due to my adventure with Steve Austin. I think that points to a needed activity for this blog: more discussion of what the folks at "Answers in Genesis" are up to. This is even more important, IMO, given their attempts at "addressing" some of the standard geological facts that are used to demonstrate this diluvian model is hooey. It's no use trotting out standard arguments if the creationists feel like they have a perfectly valid counter. It's time to update our database of counter-counter-claims.

But parrying YEC's is tedious, and no fun if it's all that all the time. So it's time to bring things back to some snails. Particularly Ice Age snails and the modern snail fauna of the Upper Mississippi Valley. Consider the following two photos:


Some recent woodland snails from southwestern Wisconsin:



Common late Pleistocene (ca. 20ka) snails from southwestern Wisconsin and southeastern Minnesota:



Three important points - one of which requires some background info, which I've touched upon in much earlier posts (and we'll revisit in the future). The other two can be seen in the above photos. One is that the "modern" snail fauna is much more diverse and second, the modern fauna displays a very wide range in body shape and size with a much bigger "upper limit." Just from this observed fact, we can start to ask some questions:

  • What was the timing of snail dispersal? Did the modern fauna appear before the ice age snails left?

  • Was this faunal transition all-at-once, or did individual species expand/adjust their range according to their own needs?

  • Do the changes in snail fauna (body size, range limits, etc.) imply something about climate change?

  • How are fossil shells preserved in the sedimentary record, and how does this affect our ability to use their shells as clues to ancient conditions?



Okay, that's enough for now. A big hello to all my new visitors - feel free to peruse the archives, leave a message, or whatever.

Little crawly creepies of the early Cambrian

I think I'll switch gears for a moment. One of the things I often do is create illustrations - either for my own research, or for things like museum exhibits. When I worked at the UW-Madison Geology Museum, I put together several drawings for our burgess shale materials:

Molaria is a rather unassuming arthropod.

The fancy trilobite, Ogogygopsis, which has more "g's" in its name than most animals. It's also a fairly demure (by trilobite standards) specimen.

Hyoliths are just strange. I find them all over the Upper Cambrian here in Wisconsin - although some of the cones might be conulariids - stay tuned.

One of the more flamboyant, but recognizable trilobite relatives is Marella.


Another relatively unassuming arthropod is Burgessia, but what's cool about this critter is that many of them leave behind a dark stain on the shale in the shape of their gill structures.

One thing that natural history reconstruction is good for is that it takes a 2-dimensional smear and "re-inflates" it for people to see. And many of these things are an inch or two long, so it's useful for those that can't get close to the display case.

Update:
Given the "outreach" potential of blogs, here are two other threads that may interest folks:

Happy Birthday!

I was reminded by Callan over at NOVA geoblog that today, October 23rd, is the date at which Archbishop James Ussher arrived at by backtracking all of the biblical "begats." How he traced the "pre-begat" time before Adam and Eve isn't quite clear, nor did he provide a correction factor to address the uncertainty related to the wives of Cain and Abel. But I digress...

If you read it literally, the Earth took physical form a mere 4,004 years BCE (before "common" era - whose era it is common to, I'm not sure). That's a whole lotta geology to fit into a short time. I guess it's up to researchers like the ones mentioned in my last post to fit all of that change into a catastrophic model. How a frictionless fault system also leaves large gouges and striations in the rock is beyond my understanding, however.

Young-Earth Creationism at GSA

It is not a little ironic that the 2009 national meeting of the Geological Society of America (GSA) provided the option to spend an entire day talking about Darwin's contributions to geology and a chance to spend a day on Mount St. Helens with a young-Earth creationist. I wonder how many people on that field trip were "in on the take." And how many were completely clueless? I know that without the connectivity of social networking, I would have been completely duped. Here, I intend to sketch my thoughts regarding what is going on with the young-Earth movement and suggest how we, as geologists, might deal with this apparent rise in anti-science.

I can imagine the dilemma the GSA field trip committee found themselves in. Here was a field trip proposal submitted by one of the strongest supporters of a young-Earth and flood geology, Dr. Steven Austin. On one hand, it is clear to anyone who follows the actions of politically motivated groups such as the Institute for Creation Research that this would be used as a badge, a sort of hallmark of acceptance of their ideas. If GSA allowed this field trip, it would certainly spell future trouble for all the sciences. However, to deny this trip - which on the objective analysis of the submitted trip description - would spell certain troubles of its own. In the end, GSA allowed the trip, and, while I am positive it is going to spell trouble at some later point, this trouble would have been far worse (and longer-lasting) had they disallowed the trip.

The description for field trip #425: The Dynamic Landscape of Mount St. Helens reads harmless enough. While the description does not sound scientifically rigorous, it does appear to be based on geologic concepts of landscape evolution. However, it contained neither. It followed the classic creationist methodology of reporting facts, but ignoring/omitting any discussion of causal mechanisms (or by stating things in a meaningless and hopelessly confusing fashion - see my fourth entry on this topic). By focusing on specific events and their "time-stamps," Austin et al. steered clear of some controversial statements and positions. This "stenography" also served to sever any connection between Mount St. Helens and the rest of the Earth. There was no discussion of plate tectonics, or volcano monitoring, or even how changes in stream power and sediment load can affect the behavior of the landscape. Nope, it was just a series of isomorphous declarative statements, "at this time this happened, etc."

That appears to be the limit of what a geologist does. In Austin's mind, geologists are merely God's Stenographers. Dutifully reporting what layers are there, but steering clear of any possibility that they can inform the observer about environment of deposition, or some larger scale function of the Earth's systems. For that is the realm of God, and unknowable/undefinable. When I first learned of the background for the guide on our trip, I went through a miniature version of the grieving process: denial, anger, sadness and then acceptance. At least I accepted the fact that I was on a trip with a man who's behavior is anathema to geology and I could take this opportunity to observe firsthand the young-Earth movement.

I began by studying Austin's essay on K-Ar dating of the Mount St. Helens dacite, and Dr. Kevin Henke's excellent rebuttal. I also looked up the histories behind the other listed field trip leaders. Dr. Kurt Wise is well-known and doesn't need a link. He also was not on the trip. The number of co-leaders fluctuated, but the people introduced to us as group leaders included:


  • Dr. Timothy Clary, Delta College

  • Dr. John Whitmore, Cedarville University

  • Dennis Bokorov, co-founder of Creation Encounter, LLC

  • Dr. Marcus Ross, Liberty University

  • Raymond Strom, Calgary Rock and Materials Services



I won't bother with a series of web links - suffice to say they have well-documented ties to creationist and young-Earth/flood geology projects. They have also contributed a large number of GSA abstracts in the last few years.

John Whitmore (with student co-authors) has several abstracts that focus on the Coconino Sandstone


The common theme within all of these abstracts are clearly pointing to 1) that the Coconino was deposited rapidly and 2) within a marine, not Eolian setting. The field and lab methods employed are simple, and often misused. For example, grain-size distributions were plotted as a standard distribution about a mean, the mineralogy was used as a reason to question eolian deposition, yet no systematic point counts of grains were done. Some analyses were spread over a broad area, while the stratigraphic constraint on most samples was either non-existant, or limited to thin carbonate-rich horizons interbedded within huge cross-bedded, arenitic to feldspathic sandstones.

One poster displayed a section of these thin carbonate-rich horizons (widely interpreted by most geologists to be inter-dune deposits) that was labeled as "0-12 m" although when asked, it was actually 1.2 m. The interpretation of thin sections included identification of recrystallized carbonates and ooids, plus some mica and other non-quartz minerals. The emphasis of Cheung et al. (2009) was to argue against eolian deposition of these particular layers, and, by association, the entire Coconino Sandstone. This is akin to a meteorologist going outside at dawn and sunset to observe the sky. The meteorologist sees the sky is red, pink, and orange. Ah ha! They say: these colors are not blue: therefore, the statement "the sky is blue" is clearly false [therefore, all of your atmospheric physics must be wrong]. Classic creationist logic - select only some data (which may or may not be systematically collected), then use this small specific example to falsify a generalization (often an over-generalization) and call into doubt the entire system of understanding.

Dr. Timothy Clarey


The treatment of these large fault systems as catastrophic - where rate of movement was in excess of 100 km/hr (Clarey, 2009), lubricated by a saturated water/anhydrite slurry within the Gypsum Springs Formation. While not explicitly stated, the implication is for rapid, sudden creation of the entire structural framework of the Rocky Mountains, enabled by catastrophic loading and near-frictionless lubrication via hydrostatic pressures. While his analysis and mapping of particular faults may have been reasonably accurate in his particular study region, he ignores a wide body of existing knowledge about this (and ALL) fault systems. His assertion that the Heart Mountain and South Fork Faults were superfaults, moving along a frictionless surface at over 100 km/hr is curious. Especially because of his additional statements regarding the stratigraphically younger Paleozoic carbonates experiencing ductile deformation during faulting (at least, that's how I read his abstract and talk statements - he may have assumed ductile deformation before or after faulting). This still begs an important question of how one can achieve brittle deformation within a clay-rich mudstone formation (which are very susceptible to ductile deformation), yet experience ductile deformation within a much more rigid limestone unit (limestone is typically more susceptible to brittle behavior - at least at low T/P).

For a geologist, the faulty (pun intended) reasoning behind all of these abstracts boggles the mind. All of these abstracts display a selective acceptance or rejection of the scientific method (methodological naturalism). In a larger sense, these authors have, at least to me, displayed (through informal questions and discussion) a complete lack of ability or desire to apply their findings beyond a report of their "research." This lack of application is illustrated by the fact they make no attempt to explain previous, unwitnessed events (which could point to an underlying physical mechanism for the behavior of the Earth system), nor extrapolate their observations into the future. The one small exception to this last statement is when Austin was asked about future eruptions of St. Helens - he mentioned historical eruptions being about 150 years apart, thus the next big eruption would be in about 120 years. Note that the only reason he made that prediction was because of past behavior - NOT because of an understanding of some underlying mechanism such as plate tectonics and igneous rock mechanics.

The work typified by the above abstracts can be characterized as Risky Thinking. By denying an underlying physical mechanism, there becomes no possibility of predicting the behavior of the resulting features (e.g.earthquakes or volcanoes). Without an underlying theoretical framework, the scientist is relegated to the role of stenographer, mindlessly reporting on what they observe. Darwin made a comment about the fruitlessness of this pursuit when he talked about "counting all the pebbles" in a gravel pit. There would be no point. Without an underlying theoretical framework predicting the hazardous behavior of earth systems is impossible - therefore preemptively evacuating people from a volcano, or prohibiting certain activities in areas prone to landslides and earthquake is impossible. This places the scientist, and community at large at great financial and personal risk. This is not only bad science ("cargo cult science" of the worst kind), but it is very risky behavior.

So what do we, as geologists do? Clearly,we can't make them go away - either by ignoring them, or by prohibiting them from speaking publicly. But we can, and must, refute their assertions with vigor. I think that their participation in GSA meetings has some benefit. Firstly, it provides an opportunity for the students of these young-Earth professors to experience the wide diversity of real science (even if for brief moments). It also provides a direct way to ask questions and learn what the young-Earth community is thinking and up to. Forewarned is forearmed, so to speak.

This brings up an important point about social networks. The conference at GSA held a special session on the use of social networks in teaching and research. I think the use of social networking tools such as blogs, tweets, and facebooks is vital to help make the geologic community aware of what's going on. Without it, I would not have been able to be aware of the nature of the field trip: both in its implications, but also in terms of its "science" content. In addition, I might not have pursued the background research and stumbled upon these abstracts. The activities of the young-Earth community clearly are part of a larger strategy to gain "scientific merit" for their views (this is related to the "Wedge" strategy as described by the Institute for Creation Research Discovery Institute [edit: wrong group]). Without social networking, this behavior might not have been discovered until later - at a point where response and criticism would be more complicated.

As geologists, we ignore people like Steve Austin, John Witmore, and Timothy Clarey at our peril. However, our response must be both thorough and united. Social networking can provide the first line of notification. I want to thank Jessica at "Magma Cum Laude" for her first note: without it, I - and others - would have been duped.

Quick Update

I'm waiting for my flight out of PDX. They have free wireless, so I figure I'll add a quick update:

The meeting was very successful. I made some new professional connections, and strengthened existing ones. I got a bunch of cool swag (which deserves its own post). I attended a very helpful scholarship of teaching and learning (SOTL) workshop, which I should also share with my audience. An audience that seems to have grown a bit thanks to the Geoblogger get-together and the blogroll feed on the GSA website. Kudos to GSA for being proactive about embracing blogs (and technology in general) for sharing geoscience info.

In case you've missed it, I've been providing a series of reports on my experiences with the young-Earth creationist, Steve Austin. I unwittingly signed up for a tour led by him to Mount St. Helens. It was informative, to say the least. I didn't learn anything about geology, but I did learn a lot about what the young-Earth movement is up to.

The story so far:

I'm leaving in about 45 minutes, so I should probably get to my gate. For some reason, the cheapest ticket has me traveling from Portland to Minneapolis via Phoenix. Very strange. At least I get a window seat, and perchance a view of the Grand Canyon. That would be a fitting postscript for this journey.

Update: A brief discussion about young-Earthism at GSA
