2017 Map of Weaver Ridge

About this map

The White River flows through the northwestern corner of this territory, where the borders of Utah and Colorado intersect in a landscape of deep canyons and named ridges. This 2017 survey by the U.S. Geological Survey documents the distinct topographical character of the Weaver Ridge and the Gilsonite Hills, areas inextricably linked to the region's industrial heritage. The names of Gilsonite Draw and the nearby hills highlight the presence of uintaite, a natural asphalt found primarily in this basin. Local transit is defined by a sparse network of backcountry routes, including Dragon Rd and the evocatively named Repentance, which navigate the complex terrain between Hells Hole Canyon and Cripple Horse Canyon. The map clearly delineates the jurisdictional boundary between Uintah County, Utah, and Rio Blanco County, Colorado, providing a precise look at the Public Land Survey System grids across state lines.
