[4] Several periods of glaciation have carved South Teton and the other peaks of the range into their current shapes.

[5] South Teton was first climbed on August 29, 1923, by Albert R. Ellingwood and Eleanor Davis.

[5] The easiest climbing route is via Garnet Canyon to an altitude of 9,200 feet (2,800 m).

From there a trail leads southwest towards a pass between South and Middle Teton.

A number of more difficult ascents are also done by experienced climbers, with difficulty of up to Class 5.11.
