2018 Map of Picacho Pass

About this map

Picacho Pass serves as a critical geographic gateway in Pinal County, where the desert floor meets the eastern foothills of the Picacho Mountains. This 2018 survey illustrates the sophisticated modern water management systems of the American Southwest, specifically the winding path of the Central Arizona Project Aqueduct as it cuts across the arid landscape. The map reveals a transition from the natural drainage patterns of ephemeral watercourses like McClellan Wash and Durham Wash to the structured grid of the Public Land Survey System. Local transportation is defined by a network of rural routes such as San Jacinto Rd and S Pecan Rd, reflecting the area's ongoing use for transit and desert access. This document provides a clear view of the intersection between historic mountain landmarks and contemporary infrastructure in a high-desert environment.
