The Tunnunik impact crater, formerly the Prince Albert impact crater, is a recently confirmed meteorite impact crater.[1] It is located on Prince Albert Peninsula in the NW part of Victoria Island1 in Canada's Northwest Territories.[2]
The 25-kilometer-wide (16 mi) crater was discovered in 2010 by Brian Pratt, professor of geology at the University of Saskatchewan, and Keith Dewing of the Geological Survey of Canada while they were doing an aerial survey of the region. The crater is estimated to have formed between 130 and 350 million years ago, and may have been created when a meteor a few kilometers in diameter struck the Earth.[3] The desert-like landscape of impact craters like Tunnunik can be useful in understanding the geology of other rocky planets such as Mars.[4]
It is Canada's 30th known meteorite impact feature.
