The Rio Grande snakes along the international border with Mexico, defining the southern boundary of this South Texas landscape. North of the river, the residential layout is characterized by numerous colonias, including Las Milpas, Valle Alto Number 1 Colonia, and Villas del Valle Colonia. These communities reflect the unique settlement patterns of the Lower Rio Grande Valley, often interspersed with agricultural lands and industrial sites.
