1989 Map of West of Avra

USGS Topo · Published 1989

About this map

The Avra Valley defines this arid landscape, where the seasonal waters of Blanco Wash and Brawley Wash are redirected by an extensive system of irrigation infrastructure. This late 1980s data reveals a desert floor crisscrossed by an evolving network of water management, featuring numerous wells and a series of ditches, some of which are already marked as abandoned. Industrial and utility footprints are clear, from the Tucson Compressor Station in the northwest to the pipeline and power lines that traverse the valley. Small-scale aviation is represented by several landing strips, while the small settlement of Garcia and scattered structures along Manville Road provide points of reference for local historians studying rural expansion in Pima County.
