2011 Map of Twin Peaks

About this map

Twin Peaks Lookout Cabin stands as a primary high-altitude landmark in this 2011 survey of Custer County. The landscape is defined by the significant elevations of White Valley Mountain and White Mountain, which feed a complex network of drainages including Bear Creek and Challis Creek. This topography necessitated a specific transportation network, seen here in the winding paths of Twin Peaks Rd and Challis Creek Rd, which provide access to remote features like Spruce Gulch Lake. Downstream, the presence of Mosquito Flat Dam on Challis Creek indicates managed water resources in this high-country environment. The map also identifies several distinct gulches, such as Armison Gulch and Cold Spring Gulch, which have long served as local identifiers for navigation and resource extraction in the region's steep valleys.
