2013 Map of Warren Mountain

About this map

Warren Mtn and the high elevations of the Lost River Range dominate this 2013 survey of the border between Custer and Butte counties. The landscape is defined by the high-altitude pass at Pass Creek Summit, where Pass Creek Rd provides a primary route through the steep terrain of the Challis National Forest. This area serves as a critical watershed, with numerous named drainages such as Massacre Cr, Wagon Box Cr, and Chicken Cr carving deep into the mountainsides. To the east, the topography transitions into notable geological depressions including Little Basin and the Wet Creek Basin. The map meticulously details a network of forest service and development roads, such as Nat For Dev Rd 539, which provide access to remote areas like Larkspur Canyon and Black Tail Canyon.
