The Rio Grande snakes through a complex drainage network at the border of Texas and Coahuila in this 2013 survey. The landscape is defined by massive topographic features, most notably the Reagan Canyon and Big Canyon systems that feed into the river from the north. Settlement is sparse in this arid region, though the map preserves the location of Horns Ranch near the riverbanks. The namesake of this quadrangle, Las Vegas de los Ladrones, occupies a central position on the Mexican side of the international boundary, illustrating the cross-border geography of this isolated stretch of the frontier.
