Cave Dirt Examined

SEM Micrograph of dirt from Horsethief Cave

A lot of caves are wet and muddy, but others are dry and dusty. Horsethief Cave, along the Wyoming/Montana border, is one of the latter, at least in places. Horsethief is also quite "hot"...er, I mean radioactive. After returning from a trip to the cave, I thought I'd take a closer look at some of the dirt I harvested from my coveralls.

Trip Report: LaSunder Cave

LaSunder-3

On August 5, 2006, Jess and I hopped into the car and headed to the White River Plateau for a much-anticipated trip to Lasunder Cave. After a few pit stops (coffee, bagels, and gasoline) we were finally on the road and heading out of Boulder.
