Searcher-- The other pictures didn't help as much as the first one. The rock (the way I see it) is like an aerial photo, showing where the important signs are and treasure.
Make a mold, out of kids clay and maybe you'll see more as the color will all be the same. There should be ravines and hills just like the rock someplace. Make a drawing or use the clay when hard and try to find one of the larger markers and start from there. Some where there'll be a "U" or "V" cut out of the hill side or rocks showing the opening to site. (should be).Go to the tallest hill or area and look around, you might be able to see some of the things in the rock. Go when there are no clouds and look for shadows, birds arrows, etc. Don't take the rock with you, you may lose it take the clay or map tha you make of it. Good Luck
Jacko P.S. I don't know what all the signs mean, I am learning, but am able to see beyond my nose.
