Wolf Creek

Wolfe Creek is a meteorite impact crater (astrobleme) in Western Australia.[1],[2] It is accessed via the Tanami Road 105 km south of the town of Halls Creek. The crater is central to the Wolfe Creek Meteorite Crater National Park.[3]

The crater averages about 875 metres in diameter, 60 metres from rim to present crater floor and it is estimated that the meteorite that formed it had a mass of about 50,000 kg[3], while the age is estimated to be less than 300,000 years (Pleistocene).[2]

The local Djaru (Jaru) Aboriginal people know it as Kandimalal.[3] It was brought to the attention of science after being spotted during an aerial survey in 1947, investigated on the ground two months later, and reported in publication in 1949.[4] The European name for the crater comes from a nearby creek, which was in turn named after Robert Wolfe (early reports misspell the name as Wolf Creek), a prospector and storekeeper during the gold rush that established the town of Halls Creek.[5]
