Kofa Mountains dominate this arid landscape in Yuma County, defining a region characterized by complex drainage patterns and sharp topographic relief. The terrain is marked by essential water catchment points such as Raven Tank, Yaqui Tanks, and Moonshine Tank, which provided vital resources in this desert environment. Notable landmarks like Polaris Mtn and the striking Natural Arch stand near the intersection of several significant washes, including Hoodoo Wash and Kofa Dam Wash. In the southern reaches, Kofa Butte rises above Moonshine Gulch, illustrating the erosional forces that have shaped these desert highlands. This 2014 survey records the traditional names of passes and water features that have long guided travel through the Big Horn Pass and across the Yaqui Wash.
