Mining claims and desert springs define this mid-century view of the Arizona interior, where the Big Sandy River and Santa Maria River converge to form the Bill Williams River. The landscape is transitioning during this 1960s survey as the Alamo Reservoir project begins to take shape, with blue hatching indicating future inundation zones near Alamo Crossing. The map preserves the location of the former mining town at Signal (Site) and a dense concentration of mineral works across the Rawhide Mountains and Artillery Mountains. Researchers will find numerous named shafts including the Cactus Queen Mine, Bonanza Mine, and the Black Diamond Mine. These remote sites are linked by a network of jeep trails and Signal Road, reflecting the rugged industrial activity that persisted long after the initial frontier boom.
