Scatman, you are really making this super easy. I have been here many many many a time. First these meadows are the ones that one passes thru right before crossing Castle Creek as one goes up the Upper Yellowstone River Drainage in the Teton Wilderness.
Then this mountain ... It is just a part of what on the maps is called Thunder Mountain. This mountain and cliffs, here in the photo, is actually at the end of the North Arm of Thunder Mountain.
I climbed this peak some years ago. Near the top found an old Bighorn Sheep Rams Skull which I packed out and I still have. It was late in the summer, in a drought year next to a big melting snowbank. Also nearby was the size of a football field that was filled with the stone chips where the Indians sat and made arrowheads out of Petrified Wood.
Great Great Great Country!!!!!!!
