2013 Map of Sinker Canyon

About this map

Sinker Canyon serves as the central geological feature of this Owyhee County landscape, where the high desert terrain is defined by deep drainage basins and remote cattle ranching outposts. Gilmore Ranch and Spring Ranch stand as primary centers of human activity in an area where water management is critical to the local economy. The sophisticated infrastructure of the Murphy Mutual Canal and the Hulet-Sinker Cr Reservoir illustrates the engineering required to sustain agriculture and livestock in this arid environment. Roads like Silver City Rd and Sinker Creek Rd connect these remote points, following the natural contours of the land through Diamond Basin and across numerous seasonal waterways including Fossil Cr and Bates Cr.
