The Rio Grande serves as the primary geographical and political anchor for this borderland area, marking the dividing line between the United States of America and Estados Unidos Mexicanos. This 2010 survey focuses on the river's path through the southern reaches of the Laredo West area, where the international boundary follows the winding waterway. The landscape is defined by the hydrologic boundary of the river, providing a precise look at the border corridor at the start of the decade. As an OE (Outside Entities) quadrangle, it records the essential international demarcation and water features that define the region's geography and administrative limits.
