Wood Buffalo National Park is the largest national park of Canada at 44,741 km2 (17,275 sq mi). It is in northeastern Alberta and the southern Northwest Territories. Larger in area than Switzerland, it is the second-largest national park in the world. The park was established in 1922 to protect the world's largest herd of free-roaming wood bison. They became hybridized after the introduction of plains bison. The population is currently estimated at 3,000. It is one of two known nesting sites of whooping cranes. The park ranges in elevation from 183 m (600 ft) at the Little Buffalo River to 945 m (3,100 ft) in the Caribou Mountains. The park headquarters is in Fort Smith, with a smaller satellite office in Fort Chipewyan, Alberta. The park contains one of the world's largest fresh-water deltas, the Peace-Athabasca Delta, formed by the Peace, Athabasca and Birch rivers. It is also known for its karst sinkholes in the north-eastern section of the park. Alberta's largest springs (by volume, with an estimated discharge rate of eight cubic metres per second), Neon Lake Springs, are in the Jackfish River drainage. Wood Buffalo is located directly north of the Athabasca Oil Sands. This area was designated in 1983 as a UNESCO World Heritage Site for the biological diversity of the Peace-Athabasca Delta, and for the population of wild bison. It is the most ecologically complete and largest example of the Great Plains-Boreal grassland ecosystem of North America. On June 28, 2013, the Royal Astronomical Society of Canada designated Wood Buffalo National Park as Canada's newest and the world's largest dark-sky preserve. The designation helps preserve nighttime ecology for the park's large populations of bats, night hawks and owls, as well as providing opportunities for visitors to experience the northern lights.
History
Before the park
This region has been inhabited by human cultures since the end of the last ice age. Aboriginal peoples in this region have followed variations on the subarctic lifeway, based around hunting, fishing, and gathering. Situated at the junction of three major rivers used as canoe routes for trade: the Athabasca, Peace and Slave rivers, the region that later was defined as the national park was well travelled by indigenous peoples for millennia. In recorded times, the Dane-zaa (historically called the Beaver tribe), the Chipewyan people, the South Slavey (Dene Thaʼ), and Woods Cree people inhabited the region, where they sometimes competed for resources and trade. The Dane-zaa, Chipewyan, and South Slavey speak (or spoke) languages from the Northern Athabaskan family. These languages are common also among the peoples in the regions to the north and west of the park, who call themselves the Dene collectively. The Cree, by contrast, are an Algonquian people. They are thought to have migrated here from the east within the timeframe of recorded history, as most Algonquian-speaking peoples are along the Atlantic coast, from Canada and south through much of the United States. Sometime after 1781, when a smallpox epidemic decimated the region, the Dene and Cree made a peace treaty at Peace Point through a ceremonial pipe ceremony. This is the origin of the name of the Peace River that flows through the region: the river was used to define a boundary between the Dane-zaa to the North and the Cree to the South. Explorer Peter Pond is believed to have passed through the region in 1785, likely the first European to do so, followed by Alexander Mackenzie three years later. In 1788 British fur traders established posts at Fort Chipewyan, just east of the current boundaries of the park, and Fort Vermilion close to the west. Fur traders followed the First Nations in using the Peace River as part of their network of canoe routes for the North American fur trade. The Métis people, descendants initially of European traders and indigenous women, developed as another major ethnic group in the region. After nearly another century of domination by the Hudson's Bay Company, Canada purchased the company's claim to the region. Agriculture was never developed in this part of Western Canada, unlike to the south. Hunting and trapping remained the dominant industry in this region well into the 20th century, and are still vital to many of its inhabitants. Following the Klondike Gold Rush of 1897, the Canadian government was keen to extinguish Aboriginal title to the land. It wanted to be able to exploit any mineral wealth found in the future without having to contend with possible objections from First Nations. The Crown signed Treaty 8 with these peoples on 21 June 1899, acquiring much of the territory as Crown land.
