The Continental Divide serves as the high-altitude spine of this landscape, marking the boundary where the Beaverhead National Forest in Montana meets the Salmon National Forest in Idaho. At this intersection of Lemhi and Beaverhead Counties, the terrain is defined by steep drainages and prominent peaks, including the high-reaching Baldy Mtn. High-elevation water features like Morrison Lake and Lake Gulch sit north of the ridge, while a network of creeks including Tenmile Cr, Clear Cr, and Poison Cr carve deep paths through the timbered slopes. The map also delineates ಹಲವಾರು numbered parcel blocks and the rugged topography of Horsethief Canyon and Long Canyon. This 2017 survey provides a precise modern look at the remote wilderness areas and forest service boundaries along the Idaho-Montana state line.
