Teton Range

Teton Range, part of the Rocky Mts., NW Wyo. and SE Idaho, just S of Yellowstone National Park. The highest peaks are within Grand Teton National Park, with Grand Teton (13,747 ft/4,190 m) the highest peak in the range. Teton Pass (8,431 ft/2,570 m) and Phillips Pass (10,700 ft/3,261 m) are just south of the park. The Teton Range includes part of Targhee National Forest, and it is also a source for the Teton River. The first recorded person to see (c.1807) the range is American fur trapper John Colter, a member of the Lewis and Clark Expedition. Fur trappers, traders, and mountain men followed suit to frequent the range in the first half of the 19th cent.
