We finally arrived in Shell, Wyoming Sunday night, with no more major adventures after the flat tire on Friday. As we drove through the Bighorn Mountains on US Highway 14, Tim spotted a moose (there turned out to be four of them); this was quite exciting, as neither of us had ever seen a wild moose before.

There was some interesting geology on the drive up into the Bighorns, between Dayton and Burgess Junction. I unfortunately didn’t have time to examine it in detail, but hopefully I can return sometime in the next few weeks. Even from the car there was some cool stuff, like this normal fault (I think this was in the Pennsylvanian Tensleep Formation, but it might be the Mississippian Madison Limestone):

There was also this rather chaotic fold:

I’m not sure, but I think this is a fold that was cut in half by a fault. The light colored rocks are Tensleep Formation. The streak of red might be a sliver of the overlying Permian Goose Egg Formation; the Goose Egg was visible in the next roadcut.

Tomorrow we’re going to try to drive out to the Two Sisters site. There has been a lot of rain here the last few weeks, so we’ll have to see if we can actually get to the site.
