image: Kurt Kjær collecting sand samples at the front of Hiawatha Glacier. This sand was transported by the glacier from the bottom of the impact crater to the ice margin, and it has yielded a wealth of information on the impact. This material relates to a paper that appeared in the Nov. 14th, 2018, issue of Science Advances, published by AAAS. The paper, by K.H. Kjær at University of Copenhagen in Copenhagen, Denmark, and colleagues was titled, "A large impact crater beneath Hiawatha Glacier in northwest Greenland." view more
