The Rio Grande serves as a defining boundary along this stretch of the Texas border, where the land meets the Estados Unidos Mexicanos at the Garceno Bend. This 2022 survey captures a complex network of colonial settlements and family-named communities clustered near the river and primary roadways. Dense residential patterns are visible in Roma, Escobares, and the numerous colonias like Loma Vista Colonia and San Juan Colonia that line the transit corridors.
