2021 Map of Coolidge Dam

About this map

The Coolidge Dam serves as the central engineering landmark of this desert landscape, holding back the waters of the San Carlos Reservoir at the junction of the Gila River and Soda Canyon. The surrounding terrain is characterized by the high peaks of the Hayes Mountains and the deeply incised paths of Jerusalem Canyon and Hawk Canyon. This area, marking the boundary between Gila and Pinal Counties, highlights a sparse settlement pattern typical of the arid interior, where named locations like Poverty Flat and numerous springs, including Tincup Springs and Grapevine Spring, indicate the historical importance of water sources. The complex topography near the Needles Eye illustrates the narrow, difficult passages through the mountains that defined early access and travel through the canyon systems.
