Meteor Crater in Arizona was the first terrestrial structure to be widely recognized as a meteorite impact scar and has probably been more intensively studied than any other impact crater on Earth. We have discovered something surprising about its mode of formation — namely that the surface-impact velocity of the iron meteorite that created Meteor Crater was only about 12 km s−1. This is close to the 9.4 km s−1 minimum originally proposed but far short of the 15–20 km s−1 that has been widely… Expand
