About this map

The Continental Divide winds along the crest of the Bitterroot Range, marking the high-altitude border between Beaverhead County, Montana, and Lemhi County, Idaho. This remote mountain landscape is defined by its dramatic hydrology, where seasonal drainages like Slag-a-melt Cr and Big Swamp Cr flow from the timbered slopes. High-elevation basins hold secluded water bodies such as Ovis Lake and the prominent Twin Lakes, which are accessible via the rugged Twin Lakes Rd.

Peaks like Jumbo Mtn and Hirschy Mtn anchor the terrain, while the Continental Divide National Scenic Trail provides a continuous path for those navigating the boundary between the Beaverhead National Forest and Salmon National Forest. The map details a complex network of creeks, including Little Moosehorn Cr and Moose Cr, illustrating the pristine alpine environment at the headwaters of the regional watershed.
