Sadam, i have a crazy question to ask:
What brought you to the area where you are finding these carvings? I would assume there is a story behind being here, so let us read the tale (the story of the legend, why you assume that this spot is related to treasure) and that may give some clue as to the meaning of what you are seeing.
That may pique someone's memory and get you some answers. Perhaps help you to understand what you are seeing.
It always helps when we can be pointed in the right direction, however, that is NEVER a substitute for working the site. If there is a treasure and you really want to find it ... you will still have to put the "pieces of the puzzle" together on site.
