The Rio Grande snakes through the northern reach of this South Texas landscape, defining the international boundary between the United States of America and Estados Unidos Mexicanos. This 2019 survey captures the borderlands within Starr Co, Texas, where the river serves as the primary geographical feature amidst a vast expanse of brush and open terrain. The map documents the intricate bends and sandbars of the river as it appeared in the late 2010s, illustrating the natural division between two nations. Beyond the river corridor, the landscape is characterized by its drainage patterns and subtle elevation changes, providing a clear record of the physical border as it transitioned into the modern era.
