| | Arizona Meteor Crater
Was recently in Flagstaff for Triumphest 2012, an annual British car show and decided to have a look at the Arizona Meteor Crater. Knew this had the potential to be interesting but seeing it firsthand, I have to say this is one impressive hole in the ground. Its believed to have been formed by a meteorite fragment that was little more than about 150 feet across. Some 50,000 years ago, it collided with the earth at a speed of about 26,000 miles per hour. This resulted in a crater with an approximate circumference of 2.4 miles and a depth of some 500 feet.
