Challis National Forest dominates this section of the Idaho interior, defined by high-altitude drainage systems and the prominent summit of Jerry Peak. The landscape is a network of deep canyons and seasonal water sources, including Sawmill Canyon and Pecks Canyon, which funnel runoff into the larger basin below. Water remains the primary driver of the local geography, with isolated points like Howell Spring and Dean Spring providing rare reliable sources in this high-elevation terrain.
