About this map

The San Carlos Reservoir dominates the center of this landscape, where the San Carlos River feeds into the impounded waters at the triple junction of Gila, Graham, and Pinal Counties. The surrounding terrain is defined by complex desert drainages and high points, including the prominent Mt Geronimo and Rockhouse Mtn in the southwest and Flatiron Mesa to the north.

A network of remote access routes, such as Coolidge Dam Rd and Indian Rte 3, navigate the canyons that cut through the high ground. Local water sources are marked by several isolated springs, including Cottonwood Spring, Quail Spring, and Wire-Corral Spring, which served as vital landmarks in this arid environment. The map also records numerous named geographic features like Squaw Canyon and Kelly Gulch, documenting the intricate topography surrounding the reservoir's northern reaches.
