1972 Map of Tornillo
USGS Topo · Published 1974About this map
The Rio Grande serves as the international boundary between the United States and Mexico in this early 1970s survey, defining a landscape of intensive irrigation and transcontinental rail. The settlement of Tornillo sits at the heart of a complex water management system, where the Tornillo Canal and Hudspeth Main Canal divert river water into the valley. This agricultural infrastructure is supported by a network of drainage features like the Upper Tornillo Drain and the Alamo Alto Drain, which crisscross the lowlands of San Elizario Island.
