The Rio Grande forms a prominent meandering southern boundary on this West Texas borderlands survey, marking the international line between the United States and Mexico. The landscape is defined by the deep incisions of Cook Creek, Indian Creek, and Cow Creek as they drain toward the river through a network of canyons including Bear Canyon and Mesquite Canyon. This arid environment shows very sparse human habitation, centered primarily on the Watts Ranch and the site at Casa de Piedras.
