Challis National Forest land dominates the southwestern corner of this survey, where the terrain breaks sharply into deep drainage features like Cedarville Canyon and Sands Canyon. The landscape is defined by the broad, semi-arid Little Lost River Valley, which cuts a wide path from the northwest toward the southeast. This basin facilitates the primary local transportation corridor along the Little Lost River Hwy, connecting the valley's disparate points.
