Giant Canadian beaver dam can be seen from space

NPR reports on the world's largest beaver dam which is visible from space.

The Canadian beaver dam is as large a nine football fields and located in Alberta's Wood Buffalo National Park.

Dan Karpenchuk reports for the NPR newscast that "it's believed several beaver families joined forces to create the massive dam, which must have taken years to complete." He also says the dam is in an almost inaccessible part of the park, which may help explain why the beavers like that spot so much and have had enough time to make the dam so big.
