Six years ago I found a gray-colored stone weathered by ocean waters. I clearly saw a face with deep set eyes. I placed it on my desk for a few years. In 2016 I put it outside. Yesterday, I saw that the stone face has been turned green by the elements –it”lost” an eye while its mouth has closed. It’s a more natural look, but a little haunting. Call CSI!Same stone in March, 2016.
