About this map

The Rio Grande Wild and Scenic River forms a jagged international boundary along the eastern edge of this Brewster County landscape, separating the United States from Estados Unidos Mexicanos. Located within the protected expanse of Big Bend National Park, the area is dominated by the high ridgelines of the Sierra del Carmen and the Sierra del Caballo Muerto.

Historical movement through this desert terrain is traced by primitive routes such as Strawhouse Trl and Marufo Vega Trl, which navigate the steep descents into Ernst Valley and the Ernst Basin. The map captures a topography of deep drainages including Telephone Canyon, Cow Canyon, and Arroyo Venado, while the isolated Ernst Tank suggests the importance of water management in this arid environment at the southern reaches of the Texas Big Bend.
