About this map

Coolidge Dam controls the western edge of the San Carlos Reservoir in this arid landscape where the Gila River cuts through the desert. The terrain is marked by significant topographical shifts, from the heights of the Hayes Mountains and Rockhouse Mtn to the low-lying Poverty Flat. The map provides a detailed look at the complex drainage network of the region, featuring named landmarks such as Needles Eye and numerous canyons including Jerusalem Canyon and Dick Spring Canyon.

Water sources are vital markers in this environment, with several springs like Tincup Springs, Indian Spring, and Wild Horse Spring dotted across the quadrangle. The infrastructure consists largely of Bureau of Indian Affairs routes, such as Bia-600 and Bia-740, which navigate the elevation changes. The boundary between Gila Co and Pinal Co follows the course of the river and the reservoir, highlighting the geographic importance of this waterway in defining jurisdictional lines.
