Ghost Rocks

I just happened to catch this ghost rock unawares. If you look carefully at the space in the middle you can see the ghost just disappearing through the crack between the three large boulders. They are very difficult to photograph and you probably have never seen one before and it is unlikely that you will ever see a picture of one again. The rock on the right side of the picture is smiling at my attempt to capture the elusive ghost rock on film. You can just see its left eye staring at me as I take the picture.
