1971 Map of Avondale SE

About this map

The Sierra Estrella dominates this 1971 orthophotoquad, showing the raw topographic character of the Sonoran Desert in Maricopa County. Unlike a traditional line-and-symbol map, this aerial perspective reveals the intricate drainage patterns and sharp ridges of the mountain range before significant suburban expansion reached this portion of the valley. To the northeast, the braiding channels of the Gila River cut a dark, winding path through the landscape, providing a stark contrast to the surrounding arid terrain. The map captures the interface between the high desert peaks and the river valley at a time when the area remained largely undeveloped, preserving the natural flow of the alluvial fans and the structural geology of the range.
