text: The third reason is in unmasking the face on mars it says in paragraph 12 "What the picture actually shows is the martian equivalent of a butte or mesa-landform common around the American West." Then to prove it even more it says this. "It reminds me most of Middle Butte in the Snake River Plain of Idaho." "That's a lava dome that takes the form of an islolated mesa about the SAME height as the face in mar." So that just said that these "faces" are common around the American West and I'm pretty sure aliens are not on earth. So unless aliens came to earth made a face and then left without NASA seeing it would be impossible.
