About this map

The international boundary between Texas and Chihuahua is defined by the winding course of the Rio Grande Rio Bravo, where the confluence with the Conchos River marks a significant geographic junction. This 1970s survey details the binational urban centers of Presidio and the larger Ojinaga, connected by a Toll Bridge and a formal Port of Entry. The Mexican side of the river features the planned residential grids of Porfirio Ornelas and numerous agrarian settlements like San Francisco and El Tecolote.

Genealogists can trace local family landmarks such as Campo Santo Rodriguez and Campo Santo Hernandez, alongside the Haciendita Cem. The transportation infrastructure of the era is well-preserved, including the Estación Ojinaga railway stop and the A T & S F rail line entering Presidio from the north. The map also captures local agricultural efforts at La Junta Farms and the complex irrigation network indicated by the Acueducto near La Esmeralda.
