The Continental Divide forms the high ridgeline boundary of the Salmon National Forest, marking a landscape defined by steep drainages and mountain summits in eastern Lemhi County. This 2024 survey documents a network of Forest Service roads and specialized communication infrastructure, including the Salt Creek Electronic Site and the associated Salt Creek/Repeater Trail. The terrain transitions from the high peaks down into the broad Lemhi Valley, where numerous mountain streams such as Hawley Creek and Reservoir Creek emerge from canyons to join the valley floor. The map illustrates a contemporary working forest managed for both utility and natural preservation, with a distinct system of spur roads like Spr D and Spr E accessing the higher elevations of the Salmon National Forest.
