1979 Map of Fresno Wash

USGS Topo · Published 1979

About this map

Fresno Wash and Altar Wash dominate this arid landscape in Pima County, where drainage networks define the terrain between Cerro Prieto and the surrounding plains. The 1970s cattle and ranching infrastructure is highly visible, centered around Pozo Nuevo Ranch and several family-named water sources like San Rafael Well. A complex system of stock tanks, including Pozo Nuevo Tank, Lilly Tank, and Pajonal Tank, illustrates the critical importance of water management in this desert environment. Human activity is marked by a network of jeep trails, a Gaging Station on the Altar Wash, and a remote Landing Strip. The map also captures the wash confluence at Bolas Blancas, a junction where Batamote Wash meets the Altar system, reflecting the seasonal hydrology of the region.
