The Big Lost River Valley dominates the northeastern corner of this Idaho landscape, where the Big Lost River winds near early water management features like the Darlington Ditch and Rodger Ditch. These irrigation structures reflect the agricultural development of the arid basin, contrasting with the high elevations of the White Knob Mountains and Sheep Mtn that rise to the south and west. Within the boundaries of the Challis National Forest, the terrain is carved by complex drainages including Big Blind Canyon, Bedy Canyon, and Rough Canyon.
