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.

Estimates of its actual diameter range from 106 to a whooping 186 miles (170 to 300 kilometers), which if proved right could mean it's the biggest.
