2017 Map of Dark Canyon

About this map

Ashley National Forest dominates the upper half of this Duchesne County landscape, where deep drainages like Dark Canyon and Harmston Canyon cut through the high plateau. The map details a sophisticated water management network vital to this arid region, featuring the Uintah Canal and Cedarview Canal along with the Ant Reservoirs. Transportation through the canyon country is marked by essential crossings such as the Upper Uinta Canal Bridge and Lower Uinta Canal Bridge. Named local landmarks such as John Starr Flat and Henry Olsen Draw provide specific points of reference for genealogical research or historical land use studies. The terrain is further defined by a high density of water sources including Grits Spring, Mugwimp Spring, and Puppy Spring, illustrating the importance of every reliable seep and flow in the Uinta River watershed during the early 21st century.
