Hi Kammer
I just posted a couple of pics of that axe mark. Havnt worked out how to make a forum-photo link yet. The lighting wasnt ideal, but its another angle on it anyway. When I was there I was pretty convinced that it was natural, but now im looking at the pictures im not so sure...I like it as a possibility and I liked the coincidence of that axe programme being filmed when i went to check it out.
