Challis National Forest dominates this section of the central Idaho mountains, characterized by a complex network of high-elevation drainages and steep gulches. The landscape is primarily defined by its water system, where Challis Creek and White Valley Creek converge, eventually drawing from higher reaches like Pats Creek and Eddy Creek. Evidence of human movement through this backcountry is visible along Twin Peaks Rd, which provides access to the higher elevations near Jeffs Flats. In the southern portion of the survey, the terrain transitions into a series of named landforms such as Big Hill Gulch and Klug Gulch, alongside the curiously named Slab Barn Lake. The map illustrates the 21st-century management of these public lands, showing the intersections of Forest Service interests and the natural topography of Custer County.
