About this map

The Continental Divide forms a jagged spine through this high-altitude landscape on the Idaho-Montana border, marking the boundary between Salmon National Forest and Beaverhead National Forest. This 2014 survey documents a territory defined by steep drainages and prominent peaks, including Baldy Mtn, which dominates the northern portion of the range. The water system is intricate, with headwaters for Tenmile Cr, Poison Cr, and Chamberlain Cr carving out deep ravines like Horsethief Canyon and Long Canyon.

Morrison Lake is the central hydrologic feature of the eastern slope, accessed via the winding Morrison Lake Rd. The map illustrates the intersection of Lemhi and Beaverhead counties, showing how the natural topography of the divide serves as both a political and a physical barrier. The absence of major settlements highlights the protected status of these national forests, where the land is primarily managed for its natural resources and watershed value.
