2021 Map of Black Gap

About this map

The White Hills dominate the western portion of this desert landscape in southern Maricopa County, providing a stark topographical contrast to the surrounding basins. This contemporary survey by the U.S. Geological Survey illustrates a region defined by its rugged elevations and drainage systems, including the Sauceda Wash in the northeast and the northern reaches of the Sauceda Mountains at the southern border. The terrain is bisected by Route 85, which passes through the geographic notch of Black Gap and runs parallel to Blindman Butte. The map details the Public Land Survey System grid across multiple townships and ranges, while maintaining focus on the natural landmarks and sparse transportation corridors like S Potatoe Rd that serve this arid environment.
