2014 Map of Copperosity Hills

About this map

Copperosity Hills and Cathedral Rock define the central topography of this Sif Oidak District desert landscape. The area is characterized by a complex network of seasonal drainages, including Kohatk Wash, Kaka Wash, and Bitter Well Wash, which carve through the broader Kohatk Valley and Kaka Valley. This 2014 survey documents the convergence of Maricopa, Pinal, and Pima counties, a point where remote mountain ranges like the Vekol Mountains and Cimarron Mountains meet the desert floor. Human presence is centered on the settlements of Totopitk and Chiapuk, connected by tribal routes Bia-242 and Bia-342. The land use patterns here reflect the unique political and physical geography of the Sonoran Desert, where county lines bisect open ranges and traditional settlements follow the natural orientation of the valleys.
