1973 Map of Land

USGS Topo · Published 1976

About this map

The San Pedro Valley reveals a rich archaeological and historical landscape within the ancient San Juan de las Boquillas y Nogales land grant. This 1970s survey documents the surviving traces of early Arizona settlements and Spanish-era history along the San Pedro River, notably the Quiburi Mission Ruins and the site of Contention Ruins. The map captures the corridor's transition from a rail-dependent valley to a ranching and agricultural district, preserving the path of the Old Southern Pacific Railroad Grade.
