Just not a *recent* impact.

Researchers discover massive meteorite impact crater beneath Greenland’s ice sheet

The crater is a substantial 19 *miles* in diameter. It is mostly under a few thousand feet of ice , but interestingly, about half of its circumference is actually clearly visible from above as part of the covering glacier. The researchers estimate that it was created by an iron meteorite less than three million years ago, perhaps as recently as the end of the last ice age
