Challis National Forest dominates this high-altitude landscape in Custer County, where the headwaters of the Pahsimeroi River begin their descent. The terrain is defined by its drainage systems, featuring the confluence of the W Fork Pahsimeroi River and the E Fork Pahsimeroi River. These waterways, along with Mahogany Cr and Rock Cr, carve deep routes through the mountains, illustrating the complex hydrology of the northern Rockies.
