Henbury Meteorites Conservation Reserve contains 12 craters which were formed when a meteor hit the earth's surface 4700 years ago. The Henbury Meteor, weighing several tonnes and accelerating to over 40,000km/h, disintegrated before impact, and the fragments formed the craters.
The scattered fragments of the Henbury Meteorite are extremely heavy since they consist mainly of the metals iron (90 per cent) and nickel (8 per cent). More than 500kg of metal have been found on the site, the largest weighing more than 100kg. Few specimens now exist in the area.
