1982 Map of San Luis Pass

About this map

The Continental Divide winds through this high-altitude corner of Hidalgo County, marking the spine between the Animas Mountains and the San Luis Mountains. The landscape is defined by its drainage systems and water catchment, featuring a network of named stock tanks such as Big Geronimo Tank, Smith Tank, and Pendleton Tank that supported ranching operations in this arid environment. Movement through the passes and along the foothills is traced by a network of jeep trails and unimproved roads, following natural corridors like Lynch Draw and Aiken Draw. The map captures a moment in the early 1980s when this remote borderland region remained sparsely developed, dominated by the natural features of the Smuggler Hills and the strategically significant San Luis Pass. It reflects a late-century land-use pattern where topographic elevation and seasonal water sources dictated the placement of every landmark and trail.
