The Rio Grande serves as both a literal and political boundary in this 2019 survey of the South Texas borderlands, where the international line separates the United States of America and Estados Unidos Mexicanos. The landscape is defined by the tight clustering of residential developments near the river, including Roma-Los Saenz and various colonias such as Evergreen, Campobello, and De La Cruz Colonia. These settlements are interspersed with seasonal drainage features like Arroyo la Minita and Ramirez Creek that cut through the arid terrain toward the river valley.
