Meteor Crater, also known as Barringer Crater, was created by an impact approximately 40,000 years ago. The crater is located west of Flagstaff, Arizona and measures about 1200 m across and 170 m deep. The metallic impactor is a coarse octahedrite called the Canyon Diablo Meteorite. In orbit, the meteor is estimated to have been about 50 m in diameter and 300,000 tonnes in mass. About half was lost in transit through the atmosphere before it impacted the Earth's surface. Canyon Diablo Meteorite is used as a standard for sulfur isotope studies in the Geological Sciences.
