Measuring 260 metres wide and up to 30 metres deep, the divot is thought to be between 10,000 and 100,000 years old and was stumbled upon in the rich, rust coloured landscape of the Hamersley Ranges in Western Australia's Pilbara region.
According to the Earth Impact Database, a resource maintained by the Geological Survey of Canada and University of New Brunswick, only 173 such impact craters have been discovered in the world.
"I wasn't looking for it," Dr Hickman recalled in a telephone interview. "I was high up in Google Earth [the free program that enables users to scour the Earth using stitched together aerial and satellite images] when I spotted this little circular structure which struck me as odd."
Although the crater is situated about 1000 kilometres north-east of Perth and more than 300 kilometres south-east of Port Headland, it is only 35 kilometres north of the mining town of Newman in an area that has been previously surveyed.
