Barringer Meteor Crater, Arizona
35°02'N, 111°01'W; diameter: 1.186 kilometers (.737 miles); age: 49,000 years
The origin of this classic simple meteorite impact crater was long the subject of controversy. The discovery of fragments of the
Canyon Diablo meteorite, including fragments within the breccia deposits that partially fill the structure, and a range of shock
metamorphic features in the target sandstone proved its impact origin. Target rocks include Paleozoic carbonates and
sandstones; these rocks have been overturned just outside the rim during ejection. The hummocky deposits just beyond the rim
are remnants of the ejecta blanket. This aerial view shows the dramatic expression of the crater in the arid landscape.
