The Bitterroot Range defines the high-altitude divide between Shoshone County and Mineral County in this 2017 survey of the Idaho-Montana border. This high-country landscape is shaped by the headwaters of the N Fork Little Joe Cr and S Fork Little Joe Cr, with the terrain rising to prominent heights at Torino Peak and Sunset Peak. The map provides a detailed view of the remote boundary land within the Lolo National Forest and St Joe National Forest, where the complex topography includes isolated features like Diamond Lake and Cliff Lake. Steep drainages such as Hendrickson Gulch and Ann Arbor Gulch cut through the ridges, while the S Fork Little Joe Rd and Dry Cr Rd No 342 trace the narrow corridors through the forest. The presence of named points like Washout Point and Eagle Cliff highlights the verticality of the region, marking a wilderness area characterized by significant elevation changes and seasonal watercourses.
