The crater has been named the Barringer Crater in honor of Daniel Barringer, who was first to suggest that it was produced by meteorite impact. It is also referred to simply as Meteor Crater. The crater is located approximately 69 km east of Flagstaff, near Winslow in the northern Arizona desert of the United States.
The crater is about 1 mile wide and 570 ft deep. About 50,000 years ago, a meteorite traveling about 20 km/s smashed into the Arizona desert. The explosion was equal to 2.5 megatons of TNT! Over the years, geologists and other scientists have identified a number of pieces of evidence pointing to a meteoritic impact.
