Australia - Gosses Bluff Crater

[from Wiki:] Gosses Bluff (or Gosse's Bluff) is thought to be the eroded remnant of an impact crater. Known as Tnorala to the Western Arrente people of the surrounding region, it is located in the southern Northern Territory, near the centre of Australia. The original crater is thought to have been formed by the impact of an asteroid or comet approximately 142 million years ago, in the earliest Cretaceous. The original crater rim has been estimated at about 22 km in diameter, but this has been eroded away. The 5 km diameter, 180 m high crater-like feature now exposed, is interpreted as the eroded relic of the crater's central uplift. In the past the crater has been the target of petroleum exploration, and two abandoned exploration wells lie near its centre.
