About this map

Picacho Reservoir dominates this 1960s desert landscape, its waters controlled at Spillway Elev 1505 to support regional irrigation. The irrigation network is clearly defined by the Casa Grande Canal and the Florence Extension, which channel water across the arid flats toward agricultural fields beyond the map's edge. This infrastructure highlights the era's intensive water management efforts in Pinal County.

To the east, the terrain rises sharply into the Picacho Mountains, where the elevation gain is marked by a network of Jeep Trails winding through the desert scrub. Seasonal drainage is evident in the path of Brady Wash, while local transit is anchored by rural corridors like Cornman Road and Houser Road. These features collectively document a mid-century period when desert reclamation and water engineering were central to the local environment.
