About this map

Ashley National Forest serves as the backdrop for this high-elevation landscape, where water management and natural drainage systems converge. The Upper Stillwater Reservoir dominates the central terrain, collecting flows from the Rock Creek and its various tributaries including the W Fork Rock Creek and E Fork Rock Creek. This modern survey illustrates the complex alpine hydrology of the region, featuring numerous small glacial lakes such as Horseshoe Lake, Audry Lake, and Tworoose Lake tucked beneath prominent peaks.

Local landmarks like East Grandaddy Mtn and Brown Duck Mtn frame the steep topography, while names like Miners Gulch suggest the area's historical prospecting ties. The network of forest routes, including Rock Creek Road and Blindstream Road, provides access to several natural water sources such as Log Hollow Spring and Burnt Ridge Spring. The Tworoose Pass serves as a critical high-point crossing between these remote drainage basins.
