North America, United States, Wyoming—Tetons, Peak 11,350+ (Matternaught Peak)

Peak 11,350+ (Matternaught Peak). This small peak, which is prominent from Lake Taminah in Avalanche Canyon but which is only a shoulder southeast of the South Teton, was first climbed on July 25 by George Hurley and Jean Tuomi by the east ridge. Descent was made via the north ridge to the notch and then west down a couloir to the meadows in Avalanche Canyon.
