Video of the Week: Discovery of the Hiawatha Impact Crater

Researchers at the Centre for GeoGenetics and a NASA glaciologist, Joe MacGregor, have discovered an enormous crater buried beneath Hiawatha Glacier in northern Greenland. The crater’s c-shape and planar deformation of nearby quartz samples indicate that this crater was created by a massive meteor. Using ice-penetrating radar from NASA’s Operation IceBridge, researchers discovered the crater “hiding in plain sight.” It is the first impact crater found under ice.

The “Hiawatha Impact Crater” spans 19 miles wide and 1,000 feet deep, making it among the largest craters on our planet. Evidence suggests that this crater is geologically young, and the impact could’ve occurred as recently as the last Ice Age (some 12-115 thousand years ago). View this week’s Video of the Week below to learn more about the Hiawatha Impact Crater.
