The Rio Grande serves as the international boundary between the United States and Mexico in this South Texas borderland. The landscape is defined by the rapid growth of colonias south of Laredo, where residential developments like Rio Bravo Colonia and Rio Bravo Annex Colonia are densely platted alongside El Cenizo. Away from the river, the terrain transitions into ranching country, evidenced by Rugama Ranch and the open land surrounding Mendez Hills. The presence of the Rancho Blanco Airport and major transit corridors like Hwy 83 Access Rd highlight the region's importance as a transportation hub. Water features are sparse but significant, including the namesake O'Keefe Lake and the La Perla Ranch Lake Number 1, which sustain the local cattle industry in this arid environment.
