I was gobsmacked when I saw those peck marks. I was not expecting anything quite so beautiful. It made the previous two hours of fruitless searching for other carved rocks worthwhile.

Have any of you tried to make your own pecked rock art? I was just wondering how much hard work it must be, and how much time you'd have to devote to making such a piece. Presumably it must be pretty tough rock for the patterns to still be there? What kind of rock would you hit it with (something even harder I suppose)? Has anyone done any 'practical archaeology' on this? questions questions questions. I hope you've got a theory fitzcoraldo..
