On my walks with the dogs, I always come across dead or fallen trees. I find the the decaying trunks of these trees interesting, because they can be the home of many things. Rabbits, moles, mice and a whole hodgepodge of insects.
Sometime if I am lucky, I'll stumble upon a stump like this one that has decayed into an interesting shape, or a natural sculpture. You could even consider them a nature's Rorschach test. What do you see when you look at this?
Hmmmm! This log reminds me of the "Sorting hat from Harry Potter". I wonder how that would be interpreted, But I'll leave that up to you.
