2020 Map of Pinnacle Canyon

About this map

The Duchesne and Carbon County line cuts across a landscape defined by dramatic elevation changes and a dense network of water-carved corridors. The primary drainage of Nine Mile Creek snakes through the lower elevations of Ninemile Canyon, a historical passage through the region's steep geography. To the north, the terrain rises sharply toward the Bad Land Cliffs, while the southern reaches are dominated by the plateau of Horse Bench. This area is characterized by intricate side canyons such as Rock House Canyon, Pinnacle Canyon, and Devils Canyon, each contributing to a complex system of natural drainages. Transportation is limited to narrow routes following these natural paths, including Sand Wash Road and Franks Canyon Road, which provide access to this isolated portion of the Uinta Basin's southern rim.
