Bear Stone: Part One

As the title suggests, there is a distinct image of a bear in this stone. Can you spot it? Hint: I took lots of pictures of it!

There are also some interesting faces and eyes including the first few photos featuring a man with a very big nose. I think he's rather fabulous.

If you look at Photo 16, there is some kind of marking that looks like the English letters "EI." I'm assuming that's a fluke, but it's an odd one, isn't it?
