Wyoming, United States
South Teton is the fifth highest peak in the Teton Range, Grand Teton National Park, Wyoming. The peak is south of Middle Teton and is sometimes included as part of the Cathedral Group of high Teton peaks. The 40 mile (64 km) long Teton Range is the youngest mountain chain in the Rocky Mountains, and began their uplift 9 million years ago, during the Miocene. Several periods of glaciation have carved South Teton and the other peaks of the range into their current shapes.
The easiest climbing route is via Garnet Canyon to an altitude of 9,200 feet (2,804 m). From there a trail leads southwest towards a pass between South and Middle Teton. Most ascents of the summit are made from this pass. A number of more difficult ascents are also done by experienced climbers, with difficulty of up to Class 5.11.
