Friday fold: west Bighorn monocline - Mountain Beltway
While out in the field with Butch Dooley last week, making major discoveries like I do, I was very impressed with the landscape-scale west Bighorn monocline, which takes formerly horizontal Madison limestone and skews it to a westward dip where the mountains end and the intermontane basin begins. It's totally sweet. Check it out in photo form and gigapan, too.
