The Challis National Forest dominates this high-altitude landscape in central Idaho, where the Pahsimeroi River valley meets steep mountain terrain. The hydrologic network here is remarkably complex, defined by the W Fork Pahsimeroi River and E Fork Pahsimeroi River which drain the southern slopes. Alpine features like Merriam Lake and Burnt Cr Lake are positioned at the headwaters of these drainages, illustrating the glacial topography of the region. Access is provided primarily through a series of Forest Service corridors, including Burnt Creek Rd and Nat For Dev Rd 118. Smaller springs, such as Poison Springs and Squaw Creek Spring, suggest the critical importance of water sources in this dry, high-elevation environment. The absence of settlements highlights the area's use as managed wilderness and rangeland.
