About this map

The Rio Grande serves as the international boundary between Texas and Estados Unidos Mexicanos in this 2016 survey of the Big Bend region. The landscape is dominated by the massive Santana Mesa and a complex network of drainage systems including Panther Canyon and Canyon Madera. This desert terrain, characterized by deep incisions and high relief, is accessible primarily via FM 170, which follows the river's northern bank.

Water sources are scarce but significant in this arid environment, marked by Seep Spring and Trough Spring. The map illustrates the rugged isolation of southern Presidio County, where the topographic detail reveals features like Pila de los Muchachos and Arroyo Primero. The close proximity of the river and the road suggests the vital corridor for transport and boundary monitoring in this remote section of the borderlands.
