I did a search for "Turtle" and didn't get any results. If this topic has already been mentioned/discussed, I apologize for
regurgitating this small but useful piece of information.
If you ever see a turtle shell sitting in a place it shouldn't be, or a depiction of a turtle carved into a rock, or anything else even slightly resembling a turtle while out exploring, START SEARCHING THE AREA! The turtle has historically been used as an indicator that a hidden treasure is nearby. Sometimes direction and distance from the turtle to the treasure could be determined by how the turtle was posed. The turtle image was mostly used by pirates as a treasure
indicator but I've read about it's use by old prospectors and bandits as well.
If anyone is interested, I'll post a message describing the what the different turtle poses indicate.
