There was an impact crater discovered recently (2018) in Greenland beneath the Hiawatha Glacier. Maybe not as ground-breaking, but these types of discoveries do still happen.,(reply>), @Gavin Minion "lose friends, but never lose a joke" is my motto,(reply>), @Paulo Marcondes Thanks for pointing that out! Totally agree.,(reply>), An impact crater is literally ground-breaking. As tectonics. Geology rocks!,(reply>), @Hgbnk Bggj I believe this crater was an impression on the rock <i>below</i> the glacial ice,(reply>), Many small asteroids are found there too simply due to being easy to spot against a white terrain.
