Banner Summit marks the high-altitude divide between the Challis National Forest and Boise National Forest in central Idaho. This 2024 survey captures the convergence of the Custer and Boise county lines amidst the Sawtooth Range. The landscape is defined by an intricate network of alpine water bodies, including Newman Lake, Dutch Lake, Swamp Lake, and Elizabeth Lake, which feed into major drainages such as Marsh Creek and Canyon Creek.
