About this map

Alamo Lake State Park centers this 1970s landscape, where the confluence of the Big Sandy River and the Santa Maria River forms the Alamo Lake reservoir. This era of the Arizona desert shows a topography defined by heavy mining activity and vast drainage basins. The map captures a complex network of ephemeral washes like Bullard Wash and Cunningham Wash that feed into the Bill Williams River, illustrating the hydraulic connection between the surrounding mountain ranges and the central basin.

Industrial history is deeply etched into the terrain, with numerous workings such as the Black Diamond Mine, Bullard Mine, and Big Stick Mine scattered across the Rawhide Mountains and Buckskin Mountains. To the southeast, the agricultural settlement of Aguila marks the edge of the Butler Valley, providing a human anchor to a region otherwise dominated by the massive landforms of the Poachie Range and the Harcuvar Mountains.
