1993 Map of San Ambrosia Creek

About this map

The Rio Grande Rio Bravo Del Norte forms a winding international boundary through this 1993 30x60 minute series sheet, separating the Texas borderlands of Maverick Co, Dimmit Co, and Webb Co from the Mexican state of Coahuila. This cross-border perspective reveals the clustered urban footprints of Zaragoza, Nava, and Allende in Mexico, while the northern bank in the United States is defined by a dendritic network of drainages including San Ambrosia Creek, Juan Botello Creek, and Piedra Creek. The terrain is characterized by intermittent water sources and scrublands, marked by landmarks such as Cathedral Rock and Cathedral Rock Spring. The map provides a rare look at the shared geography of the Rio Grande basin at the end of the twentieth century, documenting the spatial relationship between these neighboring border communities and their shared environment.
