The Rio Grande serves as the international boundary between Starr County, Texas, and the United States and Mexico in this 2016 survey. The landscape is defined by a dense corridor of settlements and colonias following the river's path, including Escobares, Garceno, and the eastern reaches of Roma-Los Saenz. Local genealogy is anchored by sites such as the Cementerio San Antonio de Escobares near Old Escobares Hwy 83. Away from the river, the terrain transitions into a network of arroyos and family-named landmarks like Regino Ramirez and Casas. Significant drainage features including Arroyo Garceño and Arroyo los Morenos cut through the brush country toward Guerrero Lake, illustrating the complex hydrology of the borderlands. The road network, from Garceno Road to numerous loop roads, reflects the established community structure of these South Texas townships.
