All along the north coast there are literally thousands of rock piles like these. Throughout the years people have created some pretty impressive rock art by piling one rock on top of the other and so on. We were told it is an ancient fertility custom. Others informed us they were Wishing Piles…you make a pile and make a wish. My person feeling is that originally they were made by the local Indians as a way of marking the way! This then became local custom at a later date.
