Challis National Forest dominates this high-elevation terrain in Custer County, defined by a complex drainage system that feeds into the Yankee Fork. The landscape is etched by a series of numerically named waterways, including Tenmile Cr, Ninemile Cr, and Sevenmile Cr, which descend through deep valleys toward the main river branch. This network of creeks reveals the topographical logic of the region, where water routes provided the primary means of navigation through the steep interior.
