MASSIVE Crater Discovered under Greenland Ice

An international team of researchers, including a NASA glaciologist, discovered a large meteorite impact crater hiding beneath more than a half-mile of ice in northwest Greenland. The crater — the first of any size found under the Greenland ice sheet — is one of the 25 largest impact craters on Earth, measuring roughly 1,000 feet deep and more than 19 miles in diameter, an area slightly larger than that inside Washington’s Capital Beltway.

They estimate the meteor was a kilometer in diameter and may have impacted as recently as 12,000 years ago. Curiously that is around the time the Younger Dryas theory estimates a comet hit Earth (possibly several impacts) causing massive flooding and later hurtled Earth into the last Ice age.
