[JD59]

This woodland construction is the world's biggest beaver dam, which at 2,790ft is more than twice the length of the Hoover dam and can be seen from space.

The mammals use trees, mud and stone to make a type of moat where they can use their swimming skills to evade any predators.

O.O wow... That's amazing. They beat us lol.
I wonder how long they've been building that? and how much bigger it'll get.

Oh, it says they've been building it for "many months." Crazy fast. I wonder how long it'll stay, do they break down?
