Henbury is a medium octahedrite (0.9mm) iron meteorite classified IIIA. The Henbury Craters are 8 miles southwest of the town of Henbury, Australia almost 10,000 years ago. RA Alderman investigated the site in May 1931 based upon Aborigine stories. He found 13 craters, the largest of which was 720 x 360 feet. Few meteorites were found in the largest three craters indicating an explosive impact. Some of the Henbury meteorites are shrapnel shaped indicating this explosive ending and some have smooth edges indicating abrasion by an atmospheric passage.
