Challis National Forest dominates the high-elevation landscape of Custer County, Idaho, where the protected lands of the Jim McClure-Jerry Peak Wilderness preserve a system of drainages and peaks. The topography is defined by prominent summits such as Jerry Peak and the surrounding basins, including Swensen Basin to the east. Water sources are critical markers across this terrain, with several named springs like Pecks Canyon Spring, Dean Spring, and Howell Spring providing vital points of reference in an area otherwise characterized by steep canyons and seasonal creeks.
