Meteorites have been found around the crater rim, and are named for nearby Canyon Diablo , which lies about three to four miles west of the crater.
Fragment of the Canyon Diablo meteorite. In 1929, astronomer F.R. Moulton was employed by the Barringer Crater Company to investigate the physics of the impact event. Moulton concluded that the impactor likely weighed as little as 300,000 tonnes, and that the impact of such a body would have generated enough heat to vaporize the impactor instantly.

The world-famous Meteor Crater and Barringer Space Museum in Arizona is a stunning natural wonder, with a wealth of interesting stops along the way.
Impact fragmentation: when there is almost no mid-air fragmentation the fragmentation can occur upon impact. In this case the strewnfield shape can be different, usually circular. Examples include the strewn fields of the Canyon Diablo meteorite which formed Meteor Crater in Arizona, and the Australasian strewnfield.
