The Rio Grande defines the extreme northeastern corner of this 2022 survey, marking the international border between the United States and Mexico. The landscape depicted is largely open terrain, with the boundary between the Eum Usa delineated along the river's winding course. This particular quadrangle captures a very specific, river-bound segment of the borderlands in Cameron County, emphasizing the natural boundary and the geographic transition at the edge of the West Brownsville area. The map focuses on this singular hydrological and political feature, providing a clear record of the river's path at this point in the early twenty-first century.
