Here’s a terrific outcrop to start off the new year at Mountain Beltway. We’re back in the Bighorns of Wyoming here, on highway 16, traversing the southern portion of the range en route from Buffalo to South Pass City.

This outcrop was the first stop on my Summer 2011 Wyoming Energy field trip, run by Sheridan College. I aim to get that whole trip (finally) blogged this month.
