1996 Map of San Ignacio Ranch

About this map

The Tohono O'odham Indian Reservation dominates this desert landscape in Pima County, reflecting the deep cultural geography of southern Arizona. Water management is the primary narrative of this arid environment, evidenced by scattered features like a Water Tank and Well that sustain activity away from the intermittent drainages of Viopuli Wash and Aguirre Wash. The eponymous San Ignacio Ranch serves as a focal point for settlement, accompanied by a small Cem that provides a tangible link to the families and individuals who lived on this land. This survey, compiled from 1974 topography and 1996 imagery, captures the intersection of traditional reservation boundaries and early ranching infrastructure during the late twentieth century.
