1957 Map of Avondale SE

About this map

The Sierra Estrella dominates this 1957 landscape, rising sharply above the desert floor southwest of Phoenix. The map documents a critical transition between the mountain range and the Rainbow Valley, defined by the Gila and Salt River Meridian which serves as the primary survey baseline for most of Arizona. Along the northeastern edge, the Gila River Indian Reservation Boundary separates the mountain slopes from the riparian corridor of the Gila River. Settlement is sparse, represented by the small locality of Corgett and scattered Mines that suggest early mineral exploration in the foothills. The presence of a Pipe Line, Ditch, and several Well sites highlights the constant effort to manage water in this arid environment, while a Jeep Trail provides the only access into the high ridges.
