Meteor Crater, Arizona

Aerial view of Meteor Crater, Arizona. Sometimes called the Barringer Crater, after the mining engineer who first suggested that it was formed by a meteor impact. It is believed to be about 50,000 years old. The crater is in northeastern Arizona, near Winslow, and is about 200 meters (600 feet) deep and 800 meters (1/2 mile) across. Several attempts to mine the iron-rich material of the meteor were made before a visitor center was built in the 1960's. Two new minerals - coesite and stishovite - were identified here; both are high-pressure forms of silica. In recent years the crater has been used for astronaut training & studies in planet comparison.
