Some beavers were there

My father recently sent me pictures of the piece of woodlands owned by my uncles (his brothers). They have beavers dwelling in the lake on their property. They don't always see them, but they can see their work: these trees have been gnawed by them, as you can see. I must say, I find this very impressive, it's like beavers have teeth that do the work of a chainsaw. They look all cute and fluffy, not as cute as otters, but still, yet they are like the ravenous vandals of the forest.
