Book Cliffs Lizard

Just a quick post, with some nifty pictures of a big ol' lizard I ran across out in Utah recently. It's around 8 inches long or so (with the tail, mind you), and looks like some kind of skink-like little herp. Anybody got any better ID?

Anyway, enjoy:

Joe Barton - STILL a Stupid Bastard

A little over a year ago, the distinguished gentlemen from Texas, Joe Barton, proved himself an ass with an attempt to use the presence of oil in Alaska to prove that the Earth had been warmer IPSO FACTO Global Climate Change is a filthy commie lie. And we all had a good laugh, because he's an idiot.

Well, ol' Joe has stepped up to the plate with yet another complete asshole move: he apologized to BP for the government "shake-down" related to the colossal environmental Apocalypse proceeding down Gulf-a-ways. Because, of course, holding companies responsible for their disastrous mistakes and expecting them to behave in a responsible manner is simply un-American. Pretty awesome, Joe! Here's a short clip of the current favorite for "oily sycophant of the year award":



And hell, when even John Boehner thinks that you maybe stepped over the line a little, then man, you've really screwed the pooch!

The Little Grand Canyon of the San Rafael Swell

I recently spent around 2 weeks bopping around the west, and in particular looking at the completely rad geology to be seen in Utah, Our Nation's Prettiest State. Anyway, one of the places I camped at was a BLM campground south of Price, UT, called "The Wedge". The Wedge sits right in the heart of the San Rafael Swell. Anyway, at this spot, the San Rafael river has sliced clean through the uplift, exposing a a fair bit of the stratigraphy; the Permian Kaibab Limestone at the base, up through the Chinle/Moenkopi red beds and windblown Wingate Sandstone (Triassic), and finally the aeolian Navajo (Jurassic). It's a pretty spot, and one I'd highly recommend for camping and hiking, if you find yourself in the area. Below are some pictures, taken right from the campground, of this amazing area.


The late spring had apparently seen a fair bit of snow, so it's awfully green out that a way right now!


And here's a little evening light photomosaic to enjoy!

Afghanistan's Mineral "Wealth"

Apparently, Afghanistan is chock-full o' all sorts of precious metals and valuable mineral resources, at least according to the USGS (and the Pentagon Afghanistan Business development group). A recent story in the New York Times details how the USGS, with the help of some previously unstudied Afghan Geological Survey and Soviet Geological Data documents, have determined that Afghanistan has extensive deposits of lots of different kinds of minerals. These include the mundane, like copper and iron (although it appears that Afghanistan has enough of these to become a major world producer), to the more exotic, like lithium and niobium. In fact, according to the Pentagon, Afghanistan could be the "Saudi Arabia of lithium" (and, as the writers over at the Wonkette pointed out "nothing at all wrong with that sentence", right?).

The figure below was lifted from the New York Times story, and shows the current estimates, in cash money, of the value of all the various types of raw mineral resources estimated to be present in Afghanistan. It's a lot of dollars,for sure!



The science behind the estimates is pretty interesting. In 2004, the USGS started up a project to survey Afghanistan, specifically in terms of water, hydrocarbons, and mineral resources. As part of this, they also spent a fair bit of time pouring over the old Afghan Survey maps and reports (from happier times), as well as the Soviet data. Of course, a lot of these works were 30 years old or so, and hadn't been touched during the bad old days of the Taliban. But, according to the USGS, they were interesting enough to warrant updated surveys, including magnetic and gravity studies over much of the interesting mineralization zones. The USGS has a nifty page, with a lot of summaries, downloadable maps and reports, and history of the project available here. It's neat stuff, and of course, the Geology of Afghanistan is pretty interesting reading.

Although it's great that Afghanistan has something else to possibly develop that could outstrip their current economic model (which, as of right now, is based solely on opium and raw human tragedy), there are some serious concerns, of course. First and foremost, lots of countries in History have had lots of mineral wealth, and it didn't do them to well, did it (Potosi comes to mind)? Afghanistan, ripped to shreds as it is by violence, is ripe for neoimperialist exsanguination, especially if there is a feeling that some countries are "owed" a bit of wealth do to previous investment. The rampant corruption in the Afghan government goes hand in hand with the potential for disaster; apparently, the Afghan Minister of Mines has already been dismissed do to a bribe scandal that involved Chinese copper mining interests.

And, of course, that's another problem on the horizon, too; a return to the "Great Game" of empire building in central Asia seems like a distinct possibility, especially where lots of world powers congregate around raw materials. As the New York Times story points out, China is already making overtures to Afghanistan regarding expanded mining operations.

Finally, what about the environmental and social impacts of opening up mining, willy-nilly, in a dirt poor country ravaged by four decades of war and poverty? Mining is brutal, hard work, even when done right; when it's in a far away place out of public scrutiny, troubles can start (just look at Butte, Montana, or Anaconda, Montana, for examples of home-grown exploitation and environmental/health disasters as a result of poor mining practices).

One hopes that the report of untapped mineral wealth in Afghanistan is good news; it certainly would be a nice economic booster for a country that hasn't had a good decade in a few hundred years. However, the natural pessimist in me can't help but worry about the potential for corruption and further exploitation of a country that has already experienced more than it's fair share of troubles.
