South Teton

South Teton, a 12,519-foot summit in Wyoming’s Teton Range, is the fifth-highest peak in the range and part of the Cathedral Group within Grand Teton National Park. The Tetons, a 40-mile chain considered the youngest in the Rocky Mountains, began rising about 9 million years ago during the Miocene, and glaciation later shaped South Teton’s steep form. Long valued by climbers, the mountain saw its first recorded ascent on August 29, 1923, by Albert R. Ellingwood and Eleanor Davis. Most climbers approach through Garnet Canyon toward the pass between South and Middle Teton, while more difficult routes reach Class 5.11.
