Lake Superior National Marine Conservation Area, created in October 2007, is the first national marine conservation area (NMCA) of Canada created since the passing of the National Marine Conservation Areas Act in 2002. More than 70 species of fish inhabit the near-pristine waters of Lake Superior, the largest of the Great Lakes. Gulls, herons, eagles, and pelicans feed in these waters, while some also use island habitats for breeding. There may be as many as 50 shipwrecks within the Lake Superior NMCA – one of which, the Gunilda, Jacques Cousteau characterized as the most beautiful wreck in the world. The area boasts many other attractions related to geology, geomorphology, and flora and fauna. Aboriginal presence in this area dates back at least 5000 years and continues to the present day.
