About this map

The Continental Divide forms the backbone of this high-altitude landscape, serving as the literal boundary between Beaverhead National Forest in Montana and Targhee National Forest in Idaho. At the heart of this crest lies Bannock Pass, a significant mountain crossing that separates the northern and southern drainage basins. The area is defined by its complex hydrology, with waters flowing toward the Missouri and Columbia River systems from sources like Deadman Lake and Divide Creek Lake.

Downslope from the divide, the terrain is incised by numerous waterways including Deadman Creek, Nicholia Creek, and the various branches of Fritz Creek. The 1987 provisional data reflects a region of strictly managed wilderness and national forest lands, where natural features like Henderson Gulch and Pine Creek dominate the landscape over human development, marking it as a critical corridor for mountain geography and environmental history.
