The Rio Grande serves as the defining geographical and political boundary in this corner of West Texas, tracing the international divide between the United States of America and Estados Unidos Mexicanos. This 2011 survey focuses on a particularly remote stretch of the river corridor where Heath Creek joins the main channel from the north. The landscape is characterized by its isolation, with the map recording the winding path of the river and the ephemeral drainage patterns of the surrounding high desert. Because this area remains largely undeveloped, the map is a precise record of the natural hydrology and international border alignment as they existed at the start of the second decade of the 21st century.
