On Tuesday I got my first good look into the coal mines of Wyoming’s Powder River Basin. This is literally where the deer and the antelope played, until the human appetite for power began eating it up. Featured are the Jacobs Ranch and Black Thunder Mines. The latter is featured in John McPhee’s Uncommon Carriers. Great reading. Go get it. (The chapters appeared first in The New Yorker.) Black Thunder (that’s it, above) is the world’s largest coal mine. It’s owned by Arch Coal. About its Powder River mines, Arch says,

Arch had sales volume of 99 million tons of coal in 2007 in the southern Powder River Basin in Wyoming, the nation’s largest coal-supply region. This tonnage is produced at Thunder Basin’s Black Thunder and Coal Creek mines. Arch controls approximately 1.75 billion tons of reserves in the PRB.

I also shot Coal Creek, which is on the other side of another huge mine, Jacobs Ranch. Got many shots of that one too. In fact, I have all these shots in RAW, in case anybody wants a high-quality copy.
