The researchers discovered the crater two summers ago while exploring the area by helicopter for the Natural Resources Canada (NRCan) Geo-Mapping for Energy and Minerals program, and it took two years to properly assemble the geologic maps and submit their article for publication. Pratt and Dewing named the new discovery the Prince Albert impact crater after the peninsula where it is situated.
