Is that picture a turtle with a phallus for a shell on top? I can't see the turtle head for sure because of the shadow cast there, but I am pretty certain on the phallus. I have one similiar where there is a definite turtle looking sideways and when you stand on it, it is a phallus pointing at a spot, and this is among alot of slightly misleading alignments, including a very obvious one that leads to a small heart nearby laying in front of an alligator looking outcrop (trap spot)...pretty sure it is a direct pointer when sideways like that (the phallus) although it could 90 degrees to it as well, I've seen this too. It can be hard to determine which are trapped spots and which are not. They can all look equally good and can have equally good alignments to them.
I believe I see one of those rocks in the background Sandy1 is speaking of. It's white and it stands out pretty well.
