About this map

The Rio Grande forms a striking international boundary on the southern edge of this region, where the border between the United States of America and Mexico follows the river's winding path. This South Texas landscape is defined by a dense concentration of colonias and residential developments clustered along the highway corridor. Small communities such as Sullivan City, Cuevitas, and Havana sit just north of the river, surrounded by a complex network of residential zones including Las Cuevas Number 2 and Saint Claire Fisher Colonia.

Away from the river, the terrain transitions into a more grid-like pattern of long, narrow parcels. Features such as Salado Creek and Cobby Lake provide the few natural hydrologic breaks in an area otherwise characterized by infrastructure like Pipeline Road and 16 Mile Road. The county line between Starr and Hidalgo County cuts diagonally through the northern reaches, marking the boundary for genealogists tracing family roots across these two jurisdictions.
