'Dr Hickman, from the Geological Survey of Western Australia, was using Google Earth to look for iron ore when he noticed an unusually circular structure.
He sent a Google Earth picture of the structure to his colleague Dr Andrew Glickson at the Australian National University, who later visited the area and confirmed that Dr Hickman had found a particularly well preserved meteorite crater."
