It's as deep as a 60-story building and as wide as 20 football fields. More than 2 million fans could watch games from the crater rim.
But to really comprehend the vastness of Meteor Crater near Winslow, Ariz., it's worth pulling off I-40 to see it yourself.
When the meteor hit Earth 50,000 years ago, it left a crater that remains the best preserved impact site on Earth.
"If this happens again in, say, downtown Manhattan, 9 million people would be gone in seconds," says Brad Andes, president of Meteor Crater Enterprises.
Visitors can watch a 10-minute film, learn about the astronauts who trained there and go on a guided rim trail walk.
