1980 Map of Ramsey Canyon

USGS Topo · Published 1992

About this map

The Rio Grande carves a deep, winding international boundary through this portion of Val Verde Co, marking the divide between the United States and Mexico. This 1980 survey captures the stark landscape as the river enters the Amistad Reservoir and the Amistad Recreation Area. The terrain is defined by dramatic drainage systems, including Ramsey Canyon, Osman Canyon, and Rattlesnake Canyon, which cut through the high ground towards the river. A relic of earlier transit is visible in the north, where the Old Railroad Grade traverses the mesas. Evidence of cattle ranching and early resource exploration is scattered across the uplands, indicated by isolated tanks, a well, and a drill hole, while Foster Spring provides a rare natural water source near the riverbank.
