The East Fork Salmon River carves a deep central valley through this high-altitude landscape in Custer County, Idaho. This modern topographic record illustrates a complex convergence of protected lands, where the White Clouds Wilderness, Hemingway-Boulders Wilderness, and Jim McClure-Jerry Peak Wilderness meet. A network of high-country routes, including the Little Boulder Creek Trl and Sheep Creek Trl, provides access to the steep drainage systems of Narrow Canyon and the prominent Red Ridge. The drainage pattern is exceptionally intricate, defined by tributaries like Germania Creek and Big Boulder Creek that feed into the main river corridor along E Fork Rd. The map detail captures the intersection of the Challis National Forest and Sawtooth National Forest, emphasizing the vast, roadless character of the region.
