Rio Grande City serves as the focal point for this Starr County landscape, where dense residential colonia developments spread northward into the brushland. The map reveals a complex network of established neighborhoods and newer settlements, including Joseph Griggs Colonia, Garza-Gutierrez Colonia, and San Jose Colonia. This urban expansion is balanced by the natural drainage of Los Olmos Cr, which snakes through the undulating terrain of the Rio Grande Valley. To the northwest, the Rio Grande City Municipal Airport anchors the regional infrastructure, while isolated water bodies like Upper Ellison Lake and Alvarez Lake punctuate the arid landscape. The documentation of named colonias like Arredondo Colonia and Leal Colonia provides essential detail for tracing the modern growth and community identity of this border region.
