The Rio Grande serves as the international boundary between the United States and Mexico at the southwestern corner of this West Texas survey. The landscape is defined by its drainage systems and ranching infrastructure, where water sources like Chupadera Spring and Sullivan Spring provide vital points of interest in an otherwise arid environment. Higher elevations are punctuated by landmarks such as Cathedral Rock, which overlooks the winding course of San Ambrosia Creek to the west.
