2016 Map of Ramsey Canyon

About this map

The Rio Grande defines the southern boundary of this West Texas landscape, marking the international border between the United States and Mexico. This 2016 survey captures the transition from the upland desert plateau into the deep drainage systems that feed the river, now protected as part of the Amistad National Recreation Area. The terrain is defined by dramatic erosional features like Ramsey Canyon and Cold Canyon, which cut through the limestone toward the river's edge. Human activity in this arid region is sparse and primarily dictated by the path of Foster Ranch Rd, providing access to the high ground between the deep incisions of Rattlesnake Canyon and Osman Canyon. Small structures near House Canyon indicate the scattered ranching infrastructure essential for life in Val Verde County.
