About this map

Targhee Pass marks the high-elevation boundary between Montana Idaho and Montana, where the crest of the Henrys Lake Mountains meets the Centennial Mountains. This 2020 record of the landscape illustrates the convergence of national forest lands, including the Targhee National Forest and Gallatin National Forest. The map detail shows the recreational and transit infrastructure around Island Park, featuring the Henry's Lake Airport and the winding course of the Continental Divide National Scenic Trail.

Hydrological features dominate the southern basin, where Targhee Creek and Howard Creek feed toward the expansive waters of Henry's Lake. Local history is anchored by the Targhee Cem and several significant natural water sources like Howard Spring and Mountain Springs. The rugged geography is further defined by prominent summits such as Bald Peak and Lionhead Mtn, which frame the pass that has served as a critical corridor through the Rockies for centuries.
