Hello skylark I agree with oddrock, It appears to me that the outer carving appears to be a Rhino head looking to the left, horn cut off, the mouth is visable, theres a square box with a X in the lower left corner and letters of the alphabet inside and outside for some reason those on the outside are more of a symbol type than letters, if you look at it from left to right the box becomes a diamond with the letters inside the box, perhaps a ( A 5 T. ) there seems to be a notch into the bottom right, sometimes that is directional, if its a diamond it could be 2.5 miles ( league ). Sometimes you may be able to look at a near-by mountain range that matches the upper portion of the head ( ? ) for a clue. I do agree that it is more than likely a map . A trick that you may try is to get a photo of it stright up and down, walk around and stop every 3 feet or so and get a angle shot probably about 45 degrees, more information can be gotten just a little bit from each one. If someone twisted my arm till I said ouch it would cause me to say A = 1--- 5 = ---- S = 19, or Genesis chapter 5 verse 19 and thats just a guess. Good Luck dsty
