World’s Largest Beaver Dam Visible From Space,Located in Canada
The largest beaver dam ever recorded stretches 775 meters (2,543 feet) long and covers 70,000 square meters (753,474 square feet) within Wood Buffalo National Park,spanning northern Alberta and the Northwest Territories in Canada. The structure is so massive it’s visible in satellite imagery.
Researchers first identified the dam in 2007 using satellite images, noting it did not exist prior too 1980. Analysis suggests successive generations of beavers constructed the dam over several decades. Its remote location, far from roads and trails, makes ground access extremely difficult, with most observers viewing it from private sightseeing flights.
Wood Buffalo National Park is Canada’s largest national park and one of the world’s largest protected areas. Reaching the dam on foot would take days due to the challenging terrain, including extensive wetlands and boreal forest.
