About this map

Challis National Forest dominates the western half of this Custer County landscape, where deep basins and high ridges define the central Idaho backcountry. The terrain is deeply carved by the East Fork Salmon River, which winds through the southern and eastern portions of the quadrangle. High-altitude drainages such as Spud-Marco Creek and Marco Cr flow toward the river, supported by water sources like Marco Spring and Lmb Spring.

Land use is marked by a network of primitive routes and named basins, including Ziegler Basin and Joe Jump Basin. Human movement through this steep environment is traced by the Snake Trail and several light-duty roads like E Fork Rd and Spar Canyon Rd. The map illustrates a high-desert mountain environment where seasonal water sources like Alkali Springs and small gulches like Cherry Gulch are the primary landmarks for navigation and land management.
