About this map

The Rio Grande Rio Bravo Coahuila serves as the focal point for this international border region in Maverick County, where the rugged topography of South Texas meets northern Mexico. Small settlements and ranching outposts like Carmelo, Las Viboras, and Buenavista are scattered throughout the landscape, connected by a network of unimproved roads and trails. The terrain is marked by significant drainages such as Tio Bruno and Providencia, which carve through the arid geography towards the river.

This 1980s survey reflects the rural character of the borderlands before modern development, capturing names like La Gaviota, Los Sauces, and El Gato. The map includes data for both the United States and Mexico, providing a rare contiguous view across the international boundary. Genealogists and local historians can trace family-named locations such as Ricardo and Perales, which anchor the sparse residential footprint of this riverine corridor.
