This undated image courtesy of Meteor Crater, Northern Arizona, USA, shows an aerial view of Meteor Crater, near Winslow, Ariz. The world's best-preserved meteor impact site is an intriguing piece of natural history. Nearly a mile wide and over 550 feet deep, the crater isn't close to being the largest in the world _ Vredefort Dome in South Africa is over 180 miles wide _ but is impressive because limited erosion has left it virtually intact.
