Snowshoe Canyon in Wyoming’s Grand Teton National Park is a glacially carved valley formed by ice that retreated about 15,000 years ago at the end of the Last Glacial Maximum. It retains the broad U-shaped profile characteristic of glacier-cut canyons. The canyon has upper and lower sections, with its upper reaches beginning near Talus Lake at about 9,670 feet. A south branch runs between Rolling Thunder Mountain to the north and Raynolds, Traverse, and Bivouac Peaks to the south. Near the fork of the north and south branches lies Dudley Lake, and the canyon opens at Moran Bay on Jackson Lake below Eagles Rest Peak.
