WHat it is IS A TREE (not a rock), folded ova' like a piece of freakin' bread dough! Wowsers! I don't even begin to understand this one.
But I love it. I mean I love it so much that if it asked me to marry it, I would totally say yes and take care of this old man (knowing he will outlive me!) This is not only an awesome tree because of this weirdo circular appendage, but also it is one of the largest birch trees I have ever seen! The type of birch which smells like wintergreen & rootbeer in it's bark and branches.....mmmmm
