1983 Map of Candilla Canyon East

About this map

The Rio Grande Rio Bravo carves a deep, winding path along the international border between Texas and Coahuila in this 1983 survey. This arid landscape is defined by its complex drainage systems, where the meandering San Francisco Creek and the steep-walled Isinglass Canyon converge near the river's edge. The map captures the geopolitical boundary established by the Treaty of 1970, showing the United States of America and Estados Unidos Mexicanos divided by the river’s centerline. Inland, the terrain is marked by an Indefinite Boundary and the meeting point of the Terrell Co and Brewster Co lines. Human presence is sparse, indicated only by a remote Landing Strip in the northeast and occasional livestock infrastructure like a solitary Well and Tank. The intricate contouring reveals the erosional patterns of Washboard Canyon and Seminole Canyon, illustrating the stark geology of the Trans-Pecos region.
