Hey Real, that is the best looking turtle back rock I have ever seen! Wow, if the Spanish(who are the ones that generaly used turtles) didn't use that one they missed a good replica..hope it has smething on it or near it that helps you...usually there is something on the bottom and the orentation of the rock is important to the indicator on the bottom. They are often found on "the Kings trail" or way to a significant place of treasure or mine.
