About this map

The San Pedro River corridor defines this arid Pinal County landscape, flanked by the high elevations of Lookout Mtn and the distinct riparian environment of Cooks Lake. This mid-century survey documents the transition of historic transport routes, most notably the Old Camp Grant Military Road, which traces a path through the valley near the PZ Ranch. This road, a vital link in Arizona's early military and frontier history, is shown alongside the more contemporary Aravaipa Road.

Ephemeral drainages including Putnam Wash, Zapata Wash, and Coppage Wash dissect the terrain, converging toward the central river valley. Evidence of rural industry and survival in the high desert is marked by a scattered Mine and several livestock watering locations, while the Aravaipa Creek provides a significant tributary to the local water network. This record of the late 1940s landscape, updated with early 1970s revisions, illustrates the persistent ranching and mining character of the region.
