About this map

Snowyside Peak dominates this high-altitude landscape within the Sawtooth Range, marking a dramatic intersection where the borders of Elmore, Custer, and Blaine counties meet. This 2020 survey illustrates a complex hydrological network where the headwaters of the S Fork Payette River flow westward through the Boise National Forest, while sister drainages like Pettit Creek and Alpine Creek feed toward the eastern valley.

Glacial legacies are evident in the density of alpine lakes, including Edna Lake, Alice Lake, and the larger Pettit Lake nestled at the base of the mountains. The area's connectivity is defined by primitive routes like the Yellowbelly Trail and the Pettit Lake Cutoff, which provide the only access through this protected wilderness. Distinctive peaks such as El Capitan and McDonald Peak provide essential orientation points for understanding the topographical layout of the Sawtooth National Forest.
