Meteor Crater, Arizona
Meteor Crater, also known as Barringer Crater is located 18 miles west of Winslow. It was formed roughly 50,000 years ago when an asteroid about 150 feet across, weighing 300,000 tons and traveling about 27,000 miles per hour slammed into the Earth.

The crater itself is nearly a mile in diameter, nearly two and a half miles in circumference, and over 550 feet deep. In the 1960's, in preparation for the Apollo missions, Nasa astronauts used the crater as a stand-in for the lunar surface.
