No, it's just a myth. That picture had a low resolution and a particular light angle made it look like a face, but see this:

Here's what it looks like from the oblique: !'face' on mars

> What the picture actually shows is the Martian equivalent of a butte or mesa -- landforms common around the American West. "It reminds me most of Middle Butte in the Snake River Plain of Idaho," says Garvin. "That's a lava dome that takes the form of an isolated mesa about the same height as the Face on Mars."
