1983 Map of South of San Pedro Hill

About this map

The Rio Grande Bravo carves a winding path through this international boundary region, defining the border between Webb County, Texas, and the Mexican state of Nuevo Leon. This 1983 survey captures a landscape characterized by ranching outposts and intermittent drainage systems like the Uña de Gato and Espaldilla. Small settlements and named ranch sites such as Rancho Nuevo, San Javier, and El Zacate are scattered across the terrain, reflecting a decentralized pattern of land use focused on the river's resources. Near the eastern edge, Colombia and the Upper Columbia Crossing indicate a critical point of connectivity between the two nations. The map also identifies local landmarks like the Lomas Los Frentones and various named points such as El Recuerdo and Maria Luisa, providing a detailed look at the rural geography and land tenure in this borderlands corridor.
