Scientists now know the age of a massive crater hidden beneath Greenland’s ice.

Hiawatha crater, which lies under 0.6 miles (1 kilometer) of ice in northwest Greenland, formed 58 million years ago, according to a study published March 9 in the journal. science progress. While some initial estimates put the crater’s age at just 13,000 years, the new discovery means the impact occurred much earlier, at a time when Greenland was brimming with life.
