The Challis National Forest dominates this high-altitude Custer County landscape, where the Lost River Range and Pahsimeroi Mountains meet. This 2024 survey documents a territory defined by sharp drainage divides and named summits, including the prominent Grouse Creek Mtn. The hydrology is characterized by steep-walled canyons like Dead Cat Canyon and Rock Spring Canyon, which channel seasonal snowmelt into Grouse Creek and McGowan Creek.
