Falconberry Peak and the high ridges of the Challis National Forest dominate this landscape in Custer County. The terrain is defined by a dense network of drainages including Loon Creek, Indian Creek, and Cold Spring Creek, which carve through the elevations between Grouse Creek Peak and the surrounding summits. Human presence in this high-altitude environment is centered on isolated points of activity like Falconberry Ranch and Biggs Ranch, which sit along the winding watercourses. Evidence of forest management and fire observation is found at Cougar Lookout, while the southern reaches are accessible via the unpaved Grouse Creek Rd. This map documents a quiet, sparsely populated corner of Idaho where life is dictated by the steep topography and the boundaries between Custer and Lemhi counties.
