Historical Marker

Magdalena Fault


The Magdalena Mountains to the west are topped by South Baldy at 10,783 feet; Magdalena Peak at 8,152 feet. La Jencia plain to the east is bisected by Water Canyon three miles below this marker. The bench along the edge of the mountains is the Magdalena Fault, dividing the uplifted mountains from the plains below.

During World War II, New Mexico was the site of several top-secret military installations, including the Los Alamos National Laboratory, where the atomic bomb was developed. The laboratory is still one of the largest employers in the state and conducts research in fields such as nuclear energy and national security.
