1983 Map of Panther Gulch East

About this map

The Rio Grande Rio Bravo carves a deep, winding boundary between the United States of America and Mexico in this 1980s topographical study. This section of the border, where Brewster County meets Terrell County in Texas, is defined by an intricate network of desert canyons and high plateaus. Landforms like Mesa Juan Botas and the Sierra La Chulita dominate the landscape, reflecting a remote region where infrastructure is minimal. Human activity is evidenced primarily by several Landing Strips and the presence of La Chulita. The map provides a look at the arid drainage systems of San Juan and San Francisco, which feed toward the international line. This survey, compiled from 1974 aerial photography and later field checks, captures the precise topography of the Big Bend region just after the treaty of 1970 established the modern river boundary.
