Continuing Thots on the Geoblogosphere

So things are getting underway here at RaaSP central. A new semester brings with it new students, new projects, and new responsibilities. I have been hired as an Assistant Professor at a State University for a tenure-track position teaching earth-sciencey type classes. There is no geology department (I'm it), so I'm stuck with a bunch of physics professors. This is not nearly as dire as it sounds. They're a great bunch of professionals who enjoy teaching as much as research - a good fit for my interests. My wife also works at the same school, so that's also important.

Being an assistant prof requires a whole new slate of obligations. That's also fine, since many of these obligations have me interacting with interesting people who are doing interesting things. It doesn't leave me as much "free" time as I would need to have a "SOOPER BLOG!1!" That's also fine, because I like my job, and I want to stick with it. But trying to associate myself with some of the bigger names and networks of the geoblogosphere might require too much of my attention. The best blogs have near-daily content. I am lucky to have one or two days in a week where I can put something thotful together. That is also fine, because there are many good blogs out there that talk about interesting things.

But there aren't many blogs that talk about all of the things that are interesting to me. There aren't that many blogs that parse information in a way that I would prefer, or with the detail I want. So I will be content in my role as one of these lesser blogs that tosses something into the ether on a somewhat less than regular basis.

I will also be increasing my presence on our University's web presence by placing research/teaching/outreach materials there. I will be continuing my original mission of geo/snail info on this blog and linking to my other "interesting stuff." I'm also removing some of the veil of anonymity that has been this blog's MO for the past five years. I figure that one important leg in a professor's tenure track is outreach, so there will be lots of reaching out. But more so as the voice of a professional and educator, as opposed to some mysterious 17th century mathematician cum programming-language slash unit-of-pressure.

Everything I plan on doing has one primary purpose: my tenure. To get there, I will use teh blog/internets as one arm of my outreach. But as a "professional" academic, there are a few cautions to maintain:

  • Professional Affiliations:
  • I do not, nor will I represent anything but my own personal take and opinions on this blog. It will in no way be meant to represent the positions or opinions of my Department or University. As such, I will probably have to avoid some issues related to academia, while focusing more attention on others.



  • Proprietary Information:
  • Some things that I really want to share with people may have to wait - some things may represent ongoing research that will be published later. Other things may be withheld due to grant funding (I can't very well tell you where to find endangered snails if some of the money that paid for my work came from the NHI). But there are also some ongoing research projects that I will make available as they happen. The mating snail behavior, for example. Blogging is a great way to share "what's new right now." Some of this work may be part of a student project - to keep things fair to the students doing the work, I'll describe active research projects in a way that allows for the students to contribute their thoughts.



  • Copyright:
  • As a result of integrating my employment, some "things" have slightly more complex copyright issues (see also "Proprietary Info"). My "work" done for this blog may have a few extra notes about how the material should be re-used. The Creative Commons has a good system that I will utilize whenever possible.

    I'm sure there are other things that I'll think of that can/will change. For now, this site will provide a link to my University page and professional information. Other things probably don't require any kind of formal description. But, being the web, I'll probably write about some of it - it's somehow satisfying seeing one's thoughts in "print."

2009 in Review

I'm back from a nice long vacation in Hawaii. My wife and I figured that since we've been married a few years and now I finished my PhD, we should take our honeymoon (she finished her PhD just after we got married). I'd be hard-pressed to think of a better geo-holiday-cation than poking around Hawai'i, Maui, and Kaua'i for two weeks.

So I have many geology-themed Hawai'i posts in the works, plus lots of warm, tropical photos to regale you with. I took about 2,500 photos over 14 days. That's nearly 179 per day. It's no small task to sort through 14 gigabytes of holiday snaps, but I'll be sure to share some of my favorites. Here's one:


It's a 5-photo stitched panoramic view of Haleakala "crater." The crater is actually two wide erosional canyons that have joined together near the summit. There are numerous cinder and spatter cones along the crater floor, which makes for an other-worldly hike through this landscape.


I figure before I get too far involved in a self-indulgent Hawai'i geology fest, I'd wrap-up the biggest geology places/events that I experienced this year. I expect that I'll post the list now, and then spend a few posts going into detail.

So here's the list, ranked somewhat by personal importance:


10. San Raphael Swell: Coyote Gulch
9. Panther Tongue
8. Western Wisconsin Trilobites
7. Porcupine Mountains, MI
6. San Raphael Swell: The Wedge
5. San Raphel Swell: Wild Horse Canyon
4. Airplane Flights over the US
3. Grand Teton NP
2. Mt. Saint Helens/GSA
1. Hawai'i


And of course, I give pride of place to the fact that I finished my PhD this year. It's such a relief to be done. I do feel some measure of pride. However, when I see the work being done by people like Dr. Steve Austin (backstory), I realize that - in the end - it's just a piece of paper. Any schmuck can get one if they stick with things long enough. It doesn't convey me some magical power, or make my ideas any better than the next person's. But it does show that I am stubborn enough to see something through to the end, and outlast my peers. So I guess that's something.

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.

Geoblogging Survey

I really don't know if there are many geologists reading this blog - given how poorly I've attended to its needs over the last couple years. However, there are many new and wonderful geo-blogs out there. If you have one, and are interested in developing the geoblog community, take a stroll over and fill out the geoblog survey:

http://geoblogs.stratigraphy.net/survey/

It's quick and painless (at least nobody has come to pummel me yet)...
