1983 Map of Alamo Hueco Mountains

About this map

The Continental Divide winds through the high desert of the borderlands, marking a landscape defined by the Alamo Hueco Mountains and the San Luis Mountains. This 1983 survey provides a detailed view of the international boundary between New Mexico and Mexico, specifically highlighting the Antelope Wells Port of Entry and the neighboring settlement of El Berrendo. The map shows a region of cattle ranching and remote outposts, where seasonal drainages like Animas Creek and Deer Creek feed into broad basins such as the Animas Valley and Playas Valley. Land use is primarily agricultural and conservation-oriented, including the Coronado National Forest and the Big Hatchet State Game Refuge. In the southern half of the map, Mexican locales such as San Francisco and Rancho Nuevo are situated near the waters of the Rio Casas Grandes, reflecting the shared hydrological and social character of the Chihuahuan Desert region across the border.
