The Middle Fork Salmon River carves a deep corridor through this central Idaho landscape, marking the boundary between the Challis National Forest and the Boise National Forest. Located within the Frank Church-River of No Return Wilderness, the area is defined by its significant relief and lack of modern road infrastructure, relying instead on a network of backcountry trails like the Middle Fork Trl and the Sulphur Creek Trl. Remote airstrips such as the Morgan Ranch Airport and Sulphur Creek Ranch Airport provide the primary points of access for this interior wilderness. High-elevation points like Big Soldier Mtn and Morehead Mtn tower over drainages like Elkhorn Creek and Dagger Creek. Near the southern edge, the site of Dagger Falls marks a prominent point of interest along the river corridor.
