1979 Map of San Ignacio Ranch

USGS Topo · Published 1979

About this map

The Papago Indian Reservation dominates this desert landscape in Pima Co, characterized by a complex network of seasonal drainage channels and scattered ranching infrastructure. Arid terrain is defined by the Viopuli Aguirre Wash and Viopuli Wash, which dictate the placement of human activity in this part of the Sonoran Desert. The map serves as a detailed record of water management in an environment where every source is vital, marking a specific Well, a Water Tank, and a Corral used for livestock. The namesake San Ignacio Ranch stands as a primary point of interest for those tracing the history of land use and habitation in this region during the mid-1970s. The absence of major highways or dense settlements highlights the rural and secluded nature of the reservation at this time.
