Wood Buffalo National Park, located in northeastern Alberta and southern Northwest Territories, is the largest national park in Canada at 44,807 km². The park was established in 1922 to protect the world's largest herd of free roaming Wood Bison, currently estimated at more than 2,000. It is the only known nesting site of whooping cranes.
The park ranges in elevation from 183 metres (600') at the Little Buffalo River to 945 metres (3,100') in the Caribou Mountains. The park headquarters is located in Fort Smith, with a smaller satellite office in Fort Chipewyan, Alberta. Geographically the park is important; it contains one of the world's largest fresh water deltas, formed by the Peace, Athabasca and Slave Rivers. It is also known for its karstsinkholes on the Northwest Territory side. The national park is also located directly north of the Athabasca Oil Sands.
Wood Buffalo Park contains the only natural nesting habitat for the critically endangered whooping crane.
World Heritage Site
This area was designated a UNESCOWorld Heritage Site in 1983 for the biologically diversity of the Peace-Athabasca Delta, the world's largest inland delta, as well as the massive population of wild bison.
