1980 Map of Picacho Pass

About this map

The Picacho Mountains rise abruptly from the desert floor in this arid landscape south of Arizona's copper corridors. In the late 1970s, the region was characterized by ephemeral drainage systems like McClellan Wash and Durham Wash, which highlight the importance of water access in the Pinal County ranching and mining country. The map documents scattered infrastructure such as the Landing Strip and a significant north-south Pipeline, alongside specialized water points including Barnett Well (Dry) and Clemens. To the west, the Gold Bell Mine and various Prospect sites indicate the area's geological potential. Transportation is anchored in the southwest corner by the Southern Pacific railroad and the eponymous Picacho Pass, a corridor that has served as a vital desert passage for centuries.
