Sulphur Creek Ranch and its associated Sulphur Creek Ranch Airport provide a rare point of human infrastructure in this high-elevation landscape within the Boise National Forest and Challis National Forest. The geography is defined by the steep drainage of the Middle Fork Salmon River, which forms a natural boundary alongside the administrative line between Valley and Custer counties. The presence of backcountry facilities like the Morgan Ranch Airport and the Boy Scout Camp Campground highlights the area's importance for wilderness access and recreation. High points such as Big Soldier Mtn and Morehead Mtn tower over a complex network of tributaries, including Sulphur Cr and Elkhorn Cr. This map documents a remote part of the Idaho wilderness where travel is largely restricted to forest roads like Dagger Falls Rd and isolated airstrips.
