Humans built the Great Wall, but beavers have built the world’s biggest beaver dam that can likewise be seen from outer space.

Located in a virtually inaccessible part of Wood Buffalo National Park in Alberta, Canada, the dam has gained much fame recently for its impressive length of more than half a mile long. Average beaver dams in Canada are 32 feet to 320 feet long, and rarely do they reach a third of a mile.

Nearly three years after its original discovery in 2007 by researcher Jean Thie, the beaver dam has recently gained the popularity it deserves through the researcher’s recent television appearances, according to Discovery News.

The giant dam is thought to have taken more than 30 years to build by multiple generations of beavers.

“Several generations of beavers worked on it and it’s still growing,” said Thie.

Thie accidentally found the dam while tracking melting permafrost using satellite imagery and Google Earth software. Click HERE to see the dam on Google maps.
