About this map

Amistad Reservoir dominates the upper right portion of this landscape along the international border in the early 21st century. The map centers on the geopolitical boundary labeled as United States of America Estados Unidos Mexicanos, reflecting the complex water management and territorial divisions of the Rio Grande region. This specific quadrangle covers a largely undeveloped expanse of the borderlands, where the transition from terrestrial terrain to the waters of the reservoir is the primary geographical feature. The sparse collection of labels underscores the open, cross-border nature of the area, making it a clear reference for understanding the modern shoreline and the formal dividing line between Texas and Coahuila.
