The Continental Divide forms a high-altitude spine across this landscape, marking the rugged boundary between Beaverhead National Forest in Montana and the Salmon National Forest in Idaho. This high-country drainage system is defined by the Beaverhead Mountains, where numerous seasonal and perennial waters like Reservoir Creek, Hildreth Creek, and Meadow Creek originate. The presence of the Continental Divide National Scenic Trl tracing the ridge lines highlights the area's role as a critical corridor for backcountry travel and conservation.
