About this map

The Rio Grande valley south of Socorro is defined here by a complex network of irrigation and conservation efforts just after the mid-century. The Bosque del Apache National Wildlife Refuge dominates the riverside, showing the Refuge Headquarters and the vital Elmendorf San Antonio Ditch that sustained the local environment. Settlement patterns follow the river and the Atchison Topeka and Santa Fe railroad line, with concentrated activity at the San Antonio station and the nearby Elmendorf Siding.

To the west, the arid Chupadera Mountains and the massive Pedro Armendaris Grant No 34 provide a sharp contrast to the lush river bottom. Local genealogy is supported by the presence of numerous family-named landmarks, including the Jacobo Sedillo Ranch, Ray Hunter Ranch, and Padilla Ranch. This 1948 survey provides a precise record of the transition from traditional ranching and farming at Duncan Farms to large-scale federal land management.
