1941 Map of Cocoraque Butte

USGS Topo · Published 1965

About this map

The Tohono O'odham nation and surrounding Pima County desert are documented here just before the mid-century, following a 1940-1941 survey by P. C. Erickson and J. G. Collins. The landscape is defined by traditional settlements like Viopuli and Nawt Vaya situated near the western edge of the Reservation. Transportation and commerce converge at Robles Junction, where the Ajo Tucson Highway meets the Sasabe Road. This intersection serves as a vital link between the outlying cattle operations, including Cocoraque Ranch, La Tortuga Ranch, and Dill Ranch. The topography is dominated by the volcanic forms of the Roskruge Mountains and the Coyote Mountains, with the prominent Cocoraque Butte rising near the northern boundary. Natural drainage patterns are dictated by the expansive Brawly Wash and Aguirre Pass, which channel seasonal water through this arid basin.
