Haughton Crater

The Haughton meteorite impact crater, on Devon Island, Nunavut, in the Canadian high arctic, is 20 km in diameter and formed 23 million years ago. It is one of the highest-latitude terrestrial impact craters known on land (75°22'N, 89°41'W). It lies in the "frost rubble zone" of the Earth, i.e., in a polar desert environment and is the only crater known to lie in such an environment.
