Sleeping Indian Mountain
Sheep Mountain (elev. 11,219') is part of the Gros Ventre Range on the east side of Jackson Hole. Its name is derived from the Rocky Mountain bighorn sheep that can sometimes be seen on its slopes. Also unofficially called "The Sleeping Indian" because it resembles an Indian chief attired in a feather headdress, stretched out on his back.
In 1925, the northern end of Sheep Mountain slid into Gros Ventre Canyon, damming the river to form Lower Slide Lake. The slide is more than a mile long and one-half miles wide. It took only about 90 seconds to three minutes for more than 20,000 cubic yards of rock to slide into the canyon.
