Boise National Forest and Challis National Forest meet in this high-elevation Idaho landscape, where the headwaters of numerous creeks diverge from prominent ridgelines. The terrain is defined by the convergence of Valley, Custer, and Boise counties. Bull Trout Lake serves as a central landmark in the southeast, while the historic Stanley/Landmark Trail cuts through the northern reaches near Cape Horn Summit. This 2017 survey details a primitive transport network, consisting largely of forest roads and trails such as Iron-Lola Creek and Gates Creek. The map provides a clear look at the drainage patterns of the region, from the northern flow of Cape Horn Cr to the southern reach of Warm Spring Cr, illustrating how these water systems have historically dictated access through the steep terrain of Mains Ridge and Kirkham Ridge.
