An outstanding example of an extinct volcanic cinder cone, Capulin Mountain was formed as early as 10,000 years ago. In cinder cones, lava pours from cracks in the base rather than over the top. Capulin itself was the escape hatch for gases that blew lava fragments into the air where they solidified and landed red hot on the cone. In 1916 it became a National Monument.
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.
