Challis National Forest dominates this section of the central Idaho mountains, where a network of trails and forestry roads reveals the complex drainage patterns of the Salmon River mountains. The high-altitude landscape is defined by its water sources, including the headwaters of Pats Creek and the notable Slab Barn Lake in the southern reaches. Steep drainages like Cartwright Gulch and Mill Creek cut through the terrain, separated by high plateaus such as Jeffs Flats. Transportation through these backcountry reaches relies on historical routes including the Custer Motor Way and the Loomis-Eddy Creek Trl, which connect the various creek valleys. The map illustrates a contemporary era of forest management and recreational access, tracing named trails such as the Twin Peaks Road Trl and White Valley Road Trl through the protected forest boundaries.
