2017 Map of Donkey Creek

About this map

Challis National Forest land dominates the northeastern corner of this Custer County landscape, where the rising elevations of the Lemhi Range meet the high desert floor. The map illustrates a network of drainage systems and springs critical to this arid environment, including Graves Spring and several seasonal watercourses such as Goldburg Creek and Donkey Creek. The presence of the Summit Reservoir in the eastern section suggests managed water resources for the ranching or agricultural operations that depend on Summit Cr and Elkhorn Cr. Access to this remote mountain terrain is defined by a few primary routes, notably Goldburg Rd and Pahsimeroi Rd, which navigate the gaps between the Donkey Hills and the deep cuts of Cooney Canyon. This 2017 survey provides a precise view of the topography and public land boundaries at the intersection of several townships.
