The Bitterroot Range forms a significant high-altitude divide in this 2013 survey, marking the jagged boundary between Shoshone Co, Idaho, and Mineral Co, Montana. This landscape is defined by its dramatic verticality, where prominent summits like Berge Peak and Black Peak anchor the ridgelines within the St Joe National Forest and Lolo National Forest. The map detail reveals an intricate drainage system including Gold Creek and Simmons Creek, which carve deep valleys between landforms such as Leg Bone Ridge and Simmons Ridge. A limited network of forest service routes, including Gold Creek Rd and Little Joe Rd, provides the only vehicular access into this high-country wilderness. Researchers can identify isolated high-mountain water bodies such as Moore Lake and trace the complex watershed of the N-Fork Simmons Creek as it descends from the rocky slopes of Pegleg Mtn.
