About this map

Picture Rocks sits at the eastern edge of this 2021 survey, where the desert landscape of the Avra Valley meets the rising terrain of China Draw. The map documents a contemporary rural-residential grid defined by long, descriptive thoroughfares such as W Paint Horse Rd, W Snakeweed Trl, and W Garcia Ranch Rd. These family and ranch-named roads reflect the modern settlement pattern of western Pima County, where large-lot homesteads are etched into the arid basin.

Water management is the central engineered feature of the landscape, dominated by the massive Central Arizona Project Aqueduct cutting north-south across the valley floor. This infrastructure exists alongside natural drainage systems like Brawley Wash and Blanco Wash, which illustrate the seasonal hydrology of the region. From the livestock-oriented BK Tank to the irrigation corridors, the map provides a clear record of how water resources dictate land use in this part of the Arizona desert.
