The Rio Grande serves as the defining international boundary through this high-desert corridor, separating the United States of America and Estados Unidos Mexicanos. This 2011 survey documents a remote stretch where the river carves through significant geological formations, including the deep incisions of Tapado Canyon and Rancherias Canyon. The landscape is dominated by these drainages, with Canyon Colorado and Closed Canyon also feeding into the river valley. Transportation is limited to the winding path of FM 170, which parallels the river's course. This map provides a clear view of the border topography just southeast of Redford, focusing on the natural desert features and the specific crossings of the drainage networks as they met the river before the most recent decade's developments.
