I came across these interesting stones when I was taking my dog for a walk along the beach, somebody had carefully placed one on top of each other, there were quite a few of them. Fortunately I had my camera with me. I have seen these before, only inland. At one time I found an article on the internet about them calling them Obos, when I looked for information today I couldn't find a thing maybe I have the name wrong.
Anyway I am pleased with this painting and I enjoyed creating it too.
