About this map

The Rio Grande carves a deep path through the Big Bend region, serving as the international boundary between Texas and Mexico. This 1971 survey captures a remote stretch of Presidio County characterized by dramatic vertical relief and significant geological features. The landscape is defined by its drainage patterns, most notably where Colorado Canyon, Closed Canyon, and Rancherias Canyon intersect the river's course. These canyons highlight the erosive power of seasonal water in an arid environment, creating a labyrinth of steep terrain along the border.

Evidence of human activity is sparse but telling, centered primarily on a solitary Cem and a rugged Jeep Trail that navigates the ridges above Tapado Canyon. The presence of a Cave and a Spring near the river suggests historically vital points of interest for those traversing this borderland. The map provides a clear record of the river's position prior to the Boundary Treaty of 1970's full implementation in this specific sector.
