Scientists confirm massive impact crater beneath Greenland’s ice
(CNN)A team of international researchers has verified the discovery of the first meteorite impact crater ever found deep beneath the Greenland ice sheet.
Found under the Hiawatha Glacier, the crater is about 1,000 feet (300 meters) deep and 19 miles (31 kilometers) wide, according to NASA’s Goddard Space Flight Center.
It was likely formed when a half a mile (800 meter) wide iron meteorite struck northwest Greenland less than three million years ago. It was then covered in ice, hiding it from view, NASA said.
