Sawtell Peak dominates the high-altitude landscape of this 1964 survey, where the Continental Divide creates a natural boundary between the Beaverhead National Forest and the Targhee National Forest. This high country straddles the Idaho-Montana border, with the western edge of Henrys Lake and its associated Henrys Lake Flat visible in the northeast corner. The terrain is characterized by steep canyons and alpine water sources, including Lake Marie and the headwaters of Rock Creek. The presence of a Radio Tower atop Sawtell Peak highlights the mid-century integration of communication technology into these high wilderness areas. Transportation is largely limited to a network of Jeep Trails and footpaths, such as those navigating Red Rock Pass and Bootjack Pass, reflecting the area's isolation and primary use for timber management and wilderness recreation.
