After spending the bulk of Friday browsing about here, I decided to go back and take a closer look at my pictures from last Sunday.
It looks like there's some mist in the first two, both in the upper right side.
In the third picture I see a sort of humanoid pig face? I believe there is another stone backing this one, but I'm not certain. It could just be picking up the texture of that stone, but it looks so much like a human eye and brow with a piggy nose to me!
