2021 Map of Columbus Peak

About this map

Columbus Peak and the surrounding desert landscape define this segment of the Arizona backcountry near the border of Yuma and Maricopa counties. The terrain is structured by the jagged reaches of the Eagletail Mountains to the north and the Gila Bend Mountains to the south, with the expansive Copper Valley lying between them. This 2021 survey reveals a remote environment where infrastructure is limited to essential desert routes like Arlington-Clanton Well Rd and S Harquahala Hyder Rd, which navigate the arid flats and skirt prominent landmarks such as Cemetery Ridge. Drainage patterns are clearly marked by ephemeral waterways like Columbus Wash and Copper Wash, providing essential topographical context for understanding the natural movement of water through this high-relief basin-and-range geography.
