2017 Map of Black Mountain

About this map

The divide between Salmon National Forest and Challis National Forest defines this high-elevation landscape in Custer and Lemhi Counties. Centered on the towering Black Mtn, the area is characterized by dramatic topographic relief and a network of drainages including Silver Cr, Panther Cr, and the long descent of Darling-Castle Creek. Human presence is marked primarily by the winding Morgan Creek Road, which navigates the pass at Morgan Creek Summit. For those tracing the geography of the Salmon River Mountains, the map details numerous named points such as Woods Peak and Van Horn Peak, alongside isolated water features like Cougar Lake and the alpine Castle Lakes. The terrain is deeply incised by drainages such as Sams Gulch and Hogan Gulch, reflecting the complex hydrology of the region.
