text: I was talking about the NATURAL lines that appear on the mesa. The lines on the mesa are to distictive to be created. If something made it they would have wanted smooth edges as well as an even ditch. If they tried to recreate the natural look it would have looked faulty and unbeliveable. The species would have completly deformed the hill exposing its true colors. Also what reason would they have for creating a random face with the possibility of no one ever seeing it. There is no point to it.
