Description

Aerial view of Meteor Crater, Arizona. Photographed with 16mm fisheye lens, May 2002. The crater is also called the Barringer Crater, after the mining engineer who first suggested that it was formed by a meteor impact. It is about 50, 000 years old and is about 200 meters deep and 800 meters 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 forms of silica created at high temperatures and pressures. In recent years the crater has been used for astronaut training and studies in planet comparison.
