1947 Map of Red Rock

About this map

Picacho Peak and the Picacho Mountains dominate this mid-century landscape, serving as a dramatic backdrop for a corridor of transportation and agriculture in the Sonoran Desert. The Southern Pacific railroad and the Casa Grande Highway parallel one another through the Picacho Pass, connecting a series of rail-dependent settlements like Picacho, Wymola, and Red Rock. This era shows a transition from traditional ranching and mining to mechanized agriculture and military utility, evidenced by the numerous irrigation wells at Eloy Farms and Arizona Farms, alongside the Marana Basic Flying School. Local history is deeply rooted here, from the Old Sasco Ruins and Sasco Sch near the Santa Cruz River to family-held operations such as Kemper Ranch, Thompson Dairy, and the Bar V Lazy E Ranch.
