About this map

Coolidge Dam stands as the central landmark in this 2018 topographic study, where the Gila River meets the San Carlos Reservoir at the boundary of Gila and Pinal counties. The landscape is defined by complex desert drainages and elevations, including the Hayes Mountains to the northwest and the sharp contours of Rockhouse Mtn in the southeast. This survey details a network of water sources essential to this arid environment, ranging from Tincup Springs and Wild Horse Spring in the high basins to Warm Spring located near the dam itself.

A primary access corridor, Government Rd, winds through the canyons, connecting the reservoir area to remote terrain like Jerusalem Canyon and the notable Needles Eye formation. To the south, the flatlands of Poverty Flat provide a stark contrast to the surrounding ridges and the steep-walled Soda Canyon. The map records an intricate system of unpaved tracks such as RD 740 and RD 610, which trace the routes through the basins and washes of this remote Arizona territory.
