1996 Map of West of Avra

USGS Topo · Published 2002

About this map

Avra Valley defines this arid landscape, where the seasonal flow of Brawley Wash and Blanco Wash dictates the drainage of the desert floor. During the late 1990s, this area of Pima County remained largely agricultural and utility-focused, marked by a complex network of ditches and pipelines supporting the regional infrastructure. The western edge is dominated by the Ironwood Forest National Monument, preserving the undisturbed character of the Sonoran Desert against the creeping utility development nearby. The infrastructure of the era is clearly visible through features like the Tucson Compressor Station and multiple Landing Strips, indicating the area's role in transportation and energy distribution. Smaller landmarks such as BK Tank and China Draw provide specific points of reference for those tracing the historical hydrology and land use patterns of this portion of the valley.
