Wilkes land crater

This is a huge unverified impact crater found beneath the ice caps in Antarctica. But the problem is, scientist are not being able to complete their test and say that it is the world's largest crater..

In May of 2006, a group of scientists, lead by Ralph von Frese, used gravity measurements and NASA satellites to identify a 300km (200mi) mass concentration...

They also found that the mass was centered within a much larger ring like structure, visible on radar imaging of the land beneath the ice caps.

This would suggest that they had found an impact structure over 480km (300mi) in diameter, which was caused by a bolus at least 55km (34.5mi) in diameter.

This monster of a crater is believed to have been associated with the greatest mass extinction of all times, about 250 million years ago.

Unfortunately, due to the fact that the crater is buried under kilometers of ice, there are no samples to test and verify that this is the largest impact crater on earth.....
