A Stone With Personality

I love this stone. It has so much personality. I'm not sure what the square-faced ones were intended to be. They remind me of the face of a hippo, but I'm not aware of anything like that ever being in Ontario. I'm also intrigued by the hole under the bridge of the nose in the second and third photos. I'm assuming it was there in the stone and that the artist made use of it to create an interesting facial feature.
