text: Last reason: what the picture actually shows is the Martian equivalent of a butte or mesa landforms. On paragraph twelve it says " What the picture actually shows is the Martian equivalent of a butte or mesa landforms common around the America west." It also says on paragraph twelve " It reminds me most of the Middle Butte in the Snake River Plain of Idaho. That's a lava dome that takes the form of an isolated mesa about the same height as the Face on Mars." For those reasons I know that the face is a natural landform.
