The largest beaver dam on Earth was discovered via satellite imagery in 2007, and since then only one person has trekked into the Canadian wild to see it. It’s a half-mile long and has created a 17-acre lake in the northern forest — a testament to the beaver’s resilience.
Wood Buffalo National Park, the largest national park in Canada, covers an area the size of Switzerland and stretches from Northern Alberta into the Northwest Territories. Only one road enters it from Alberta, and one from the NWT. If not for people observing it from airplanes and helicopters, and satellites photographing it, little would be known about big parts of it. The park is a variety of landscapes — boreal swamps, fens, bogs, black spruce forests, salt flats, gypsum karst, permafrost islands, and prairies that extend the continent’s central plains to their northern limit. The wood buffalo in the park’s name are bison related to the Great Plains bison. In this remoteness, the buffalo descend from the original population, and the wolves that prey on them are also the wild originals. Millions of birds summer and breed here. The park holds one of the last remaining breeding grounds of the whooping crane.
Other superlatives and near-superlatives: the delta in the park’s southeast where the Peace River and the Athabasca River come together is one of the largest freshwater deltas in the world; last summer, some of Canada’s largest forest fires burned in the park and around it; and — just inside the park’s southern border — is the largest beaver dam in the world.
