The Hiawatha impact crater is covered by the Greenland Ice Sheet, which flows just beyond the crater rim, forming a semicircular edge. Part of this edge (top of photo) and a tongue of ice that breaches the crater’s rim are shown in this photo taken during a NASA Operation IceBridge flight on April 17, 2018.

Meteorite Crater Discovered Under Greenland Ice

Researchers have identified a large meteorite impact crater hiding under the Greenland ice. This giant crater appears to be result of meteor strike no longer than 12,000 years ago just at the end of the last ice age. The impact crater is hiding beneath more than a half-mile of ice in the northwest of Greenland. This crater is among the 25 largest impact craters on Earth. About 1,000 feet deep and 19 miles wide.

Considering that glacier ice can be incredibly erosive, the crater is surprisingly well preserved. The researchers first spotted the crater in July 2015 during an inspection for a new topography map beneath Greenland’s ice sheet. The map was made using ice-penetrating radar data primarily from NASA’s Operation IceBridge. The operation is a several year airborne mission to track changes in polar ice. The scientists noticed an enormous, previously unexamined, circular depression under the Glacier.

Could Ancient Alien Life Exist Below Us

Such a discovery is reminiscent of H. P. Lovecraft’s At The Mountains of Madness. Maybe we will discover signs of alien life beneath the ice that have been with us since the beginning of man without our knowledge. The curiosity of man may get the better of us, as we will eventually find something that should have been left buried and undisturbed.
