Dotting the northern coast are countless rock towers consisting of stones precariously placed one atop the other. These cairns seem destined to collapse during the next wind gust. Most are small but some are huge like this one. They are sparse in some areas and numerous in places like the Rock Wish Garden. You immediately assume they are part of a religious ceremony or cult following. Instead, they are created by tourists who want to leave their personalized mark on the island.
