If you look at this at its gigantic original size, you will be able to see petroglyphs carved into the rock in a couple of different places.

Please see David's image www.pbase.com/globalgadabout/image/155374575 to get a better idea of how we got there and also my detail shot of the Wolfman petroglyph panel on the middle right of this pano. www.pbase.com/dlgphoto/image/155287258
