2020 Map of Rock Creek

About this map

Challis National Forest dominates this central Idaho landscape, where high-elevation ridgelines and deep drainage basins define the wilderness character of the Lemhi and Custer County border. The map provides a detailed look at the complex hydrography of the region, anchored by the winding course of Loon Creek and its many tributaries, including Warm Springs Creek and Cottonwood Creek. The transport network is sparse, reflecting the remote nature of the terrain, yet it includes significant back-country routes like the Sleeping Deer Road (Winter Trail) and Nat For Dev Rd 86. Prominent topographical features such as Bridge Creek Ridge and Hot Creek Ridge divide the various creek valleys, illustrating the natural barriers that have historically dictated movement through these mountains. This survey serves as a modern record of public lands and water resources before any shifts in forest management or natural environmental change.
