USGS Topo · Published 1956About this map
The Rio Grande defines the western frontier of this South Texas landscape, serving as the international boundary between Tamaulipas, Mexico, and Zapata County. This World War II-era military tactical map highlights a region dominated by a traditional ranching economy, organized into extensive pastures named for local families and landmarks. The settlement of San Ygnacio serves as a primary hub along the river, featuring a Ferry crossing that links the two nations.
