NASA Finds Possible Second Impact Crater Under Greenland Ice
11 February 2019
A NASA glaciologist has discovered a possible second impact crater buried under more than a mile of ice in northwest Greenland.
This follows the finding, announced in November 2018, of a 19-mile-wide crater beneath Hiawatha Glacier – the first meteorite impact crater ever discovered under Earth's ice sheets. Though the newly found impact sites in northwest Greenland are only 114 miles apart, at present they do not appear to have formed at the same time.
