About this map

The Rio Grande forms the international boundary between the United States and Mexico along the southern edge of this borderland survey. In this region of the Rio Grande Valley, the residential landscape is defined by numerous colonias, representing a distinct pattern of settlement and community development. These communities, such as Valle Vista Colonia, Nina Colonia, and La Hermosa Colonia, are clustered primarily along the primary east-west transportation corridors. Near the river, Cuevitas and specialized river features like Santos Banco Number 95 and Cuevitas Banco Number 96 reflect the hydrological and political history of the meandering waterway. The northern interior transitions into larger land tracts, exemplified by the El Toro Ranch, where the grid of county roads like Sevenmile Rd and County Line Rd stretches across the brush country.
