1957 Map of Avondale SE

About this map

The Sierra Estrella dominates this landscape south of the Gila River, where steep topography meets the wide expanse of Rainbow Valley. Published from a 1957 survey, this map captures the transition from the high peaks to the arid lowlands, marked by seasonal drainages like Corgett Wash. The northeastern portion is defined by the Gila River Indian Reservation Boundary, following the river's path where irrigation infrastructure is visible through the presence of a Ditch. Small-scale human activity is scattered throughout the region, including the settlement of Corgett and several Mines tucked into the mountain foothills. Movement across this desert terrain was limited to a few improved roads and a Jeep Trail winding through the reservation lands, reflecting the remote nature of Maricopa County during the mid-century.
