The Hickman Crater (also known as the Hickman impact crater) is a newly discovered probable meteorite impact crater, 35 kilometres north of Newman, Western Australia in the Ophthalmia Range. It was discovered by Arthur Hickman, a Government Geologist with the Geological Survey of Western Australia, in July 2007.[1] The discovery was made by chance while browsing Google Earth.[2]

The crater is about 260 metres wide and 30 metres deep, and is thought to be between 10,000 and 100,000 years old, though new research suggests it may be around 50,000 years.[3] Elevated levels of siderophiles in the structure such as iridium and palladium have also been found.[3]
