About this map

The Rio Grande carves a sharp, winding boundary through this 1980s landscape, separating the United States of America from the Estados Unidos Mexicanos. This arid region in Brewster County is defined by the high elevations of the Sierra del Carmen and the Sierra del Caballo Muerto, which dominate the western portion of the sheet. Most of the terrain is protected land, including the eastern reaches of Big Bend National Park and the Black Gap State Wildlife Management Area.

International connectivity is concentrated at the Stillwell Crossing Port of Entry and the settlement of Boquillas, where the river creates a focal point for cross-border activity. Away from the water, the map details a topography of drainages like Brushy Draw and the broad, open expanse of the Llano Los Buras. Historical crossings like Heath Crossing remain noted, marking the traditional routes through this remote desert environment.
