2023 Map of Dark Canyon

About this map

Ashley National Forest dominates this Duchesne County landscape, where the high-altitude drainage systems of the Uinta Mountains shape the human and natural geography. The intricate network of springs, such as Mugwump Spring and the sequenced Russell Spring Number 1, Russell Spring Number 2, and Russell Spring Number 3, reveals the critical role of water management in this arid region. This is further evidenced by the Powerplant Canal and Pole Creek Canal, which divert flows along the Uinta River corridor. The map details a transition from the deep relief of Dark Canyon and Harmston Canyon to the level expanse of John Starr Flat. Distinctive nomenclature like Wild Horse Draw and Henry Olsen Draw reflects the area's grazing and ranching heritage, while roads such as Ute 171 Rd and Uintah Canyon Rd provide access through the complex canyon terrain.
