The Middle Fork Salmon River cuts through the northwestern corner of this high-elevation terrain, marking the boundary between Valley and Custer counties. This landscape is defined by the high divides of Soldier Ridge and Greyhound Ridge, which cradle a high-mountain lake system including Soldier Lakes, Iris Lake, and the remote Helldiver Lake. The map reveals a complex drainage network where Soldier Creek and Muskeg Creek flow through the heart of the Challis National Forest. Notable landmarks such as Mt Mills and the high-altitude Josephus Lake highlight the primary points of interest for backcountry researchers. The presence of the Josephus Lake Rd provides one of the few designated access points into this primitive area, contrasting with the numerous unnamed trails and creek beds like Float Cr and Sulphur Creek.
