Meteor Crater, Arizona

Today I visited the Meteor Crater in Northern Arizona, just East of Flagstaff. This is the site where a meteor struck earth at about 26,000 miles per hour. Since this happened about 50,000 years ago, no people were yet living in the area. The meteor left a crater about 700 feet deep and over 4,000 feet across. It has only been recently that scientists could verify that the crater was caused by a meteor and not a volcanic eruption.
In the top photo, I am sitting next to the largest fragment of the meteor recovered at the site. In the bottom photo, I am at the bottom of the crater near the location U.S. astronauts trained before landing on the moon.
