2014 Map of Blacktail Mountain

About this map

Uinta Valley serves as a focal point for this landscape, where the Duchesne River cuts through the high desert terrain. The topography is defined by a series of prominent ridges and drainages, most notably Blacktail Ridge and McAfee Ridge, which guide the flow of seasonal runoff through areas like Sand Wash and Brown Draw. This 2014 survey documents the modern layout of W Highway 35 as it follows the river valley, providing critical transit through the rural expanse of Duchesne County. To the north and south, the terrain rises sharply toward landmarks such as Blacktail Mtn and the distinctively named The Nipple. The convergence of Rock Creek with the larger river system illustrates the hydrologic patterns that have shaped land use and ranching boundaries in this part of the Uintah Basin.
