1963 Map of Red Rock

About this map

The Southern Pacific railroad corridor serves as the primary artery through this desert landscape, linking the settlements of Picacho, Wymola, and Red Rock. This era of the mid-twentieth century highlights an economy transitioning between traditional ranching and modern infrastructure. Numerous family-named homesteads and agricultural operations like La Osa Ranch, Kemper Ranch, and Thompson Dairy are scattered near the Santa Cruz River and Greene Canal, while the industrial footprint of the Saguaro Power Plant and Marana Air Park signals the growth of the Sun Corridor. Of particular interest to local historians is the Historical Marker at Picacho Pass, noting the site's significance near the base of Picacho Peak. Remote operations such as the Gold Bell Mine on Newman Peak and several Cem locations provide specific data points for genealogists and researchers tracking the Pinal and Pima county borderlands.
