A Canadian-based ecologist says he has located the world's largest beaver dam in northwestern Canada using Google satellite technology.
Ecologist Jean Thie located the 2,788-foot (850-meter) dam using Google Earth and NASA technology while researching the rate of melting permafrost in the country's far north.
Situated in northern Alberta's Wood Buffalo National Park, which straddles the Alberta-Northwest Territories border, the dam stretches more than eight football fields long, Thie said Friday.
