The Rio Grande cuts through the northwest corner of this quadrangle, defining the international boundary between the United States of America and Estados Unidos Mexicanos. This remote stretch of the river landscape is characterized by its isolation and the stark demarcation of the border. While the map is sparse in terms of named settlements, it documents the exact topographic profile and river course as it existed in 2011. For researchers of border history and the geography of the Big Bend region, this survey provides a precise look at the drainage patterns and terrain of the Chihuahuan Desert before more recent environmental changes.
