Challis National Forest dominates the high-elevation terrain of this Custer County landscape, where the White Knob Mountains rise sharply above the Big Lost River Valley. The mapping of this area reveals a complex network of canyons and gulches, including Big Blind Canyon, Marsh Canyon, and the curiously named Box Bailey Corral Canyon. Water management is central to the lower elevations, where the Big Lost River is diverted into the Rodger Ditch and Darlington Ditch to support local agricultural needs.
