The First Impact Crater Found Underneath the Greenland Ice Sheet (6 of 9)

Caption

An artist's depiction of a possible impact into the Greenland Ice Sheet. The iron meteorite penetrated seven kilometers into the Earth's crust, creating a crater that was initially 20 kilometers wide and collapsed within minutes into the final 31 kilometer crater we see today. 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."
