Canyon Diablo (Barringer Crater)
Iron meteorite (Octahedrite ; IAB)

Meteor Crater, or Barringer Crater, is an impact crater about 37 mi (60 km) east of Flagstaff and 18 mi (29 km) west of Winslow in the desert of northern Arizona, United States. The site had several earlier names, and fragments of the meteorite are officially called the Canyon Diablo Meteorite, after the adjacent Canyon Diablo.

​

Meteor Crater lies at an elevation of 5,640 ft (1,719 m) above sea level. It is about 3,900 ft (1,200 m) in diameter, some 560 ft (170 m) deep, and is surrounded by a rim that rises 148 ft (45 m) above the surrounding plains. The center of the crater is filled with 690–790 ft (210–240 m) of rubble lying above crater bedrock.

​

The object that excavated the crater was a nickel-iron meteorite about 160 ft (50 m) across. The speed of the impact has been a subject of some debate. Modeling initially suggested that the meteorite struck at up to 45,000 mph (20 km/s), but more recent research suggests the impact was substantially slower, at 29,000 mph (12.8 km/s). About half of the impactor's bulk is believed to have been vaporized during its descent through the atmosphere. Impact energy has been estimated at 10 megatons TNT. The meteorite was mostly vaporized upon impact, leaving relatively few remains in the crater.
