Rio Grande Wild and Scenic River defines the upper-left corner of this map, tracing the international boundary between Estados Unidos Mexicanos and the United States of America. This high-desert landscape is anchored by the southern extent of Big Bend National Park within Brewster Co, Texas. The terrain is marked by the course of the Rio Grande as it flows through the trans-border region, joined by smaller drainages such as Heath Cr. The map primarily showcases the vast, undeveloped desert environment of the borderlands, where the river serves as both a natural landmark and a geopolitical demarcation. This 2016 survey documents the preservation of the river corridor before it exits the park's immediate vicinity into the remote reaches of Coahuila and West Texas.
