The Prince Albert Impact Crater is a probable meteorite impact crater located on Prince Albert Peninsula, in the northwestern part of Victoria Island in Canada's Northwest Territories.[1] 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 5-kilometer-wide (3 mi) meteor struck the Earth.[2] It is Canada's 30th known meteorite impact feature.
