Challis National Forest dominates this section of Custer County, defined by a complex drainage network where numbered streams from Fivemile Creek to Twelvemile Creek converge toward the Yankee Fork. The landscape is etched with an intricate system of forest trails and primitive roads, including the Custer Trail Road and the McKay-Eleven Trail, which follow the steep contours of the Salmon River Mountains.
