This large valley was occupied by ancient Ice Age Lake Estancia some 12,000 years ago. To the north, the Southern Rockies rise to altitudes of 13,000 feet; to the northwest are the Ortiz and San Pedro Mountains; to the west are the Sandia Mountains, and to the southwest are the Manzano Mountains. Elevation 6,200 feet.

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.
