Signs on the Sand

 Remember this famous Mars face? So recently NASA found another one, here in the Earth, in Australia actually. They call it "Ghostly Face In South Australian Desert". I first though it's about upside-down face that reminds Dali paintings, but no. Can you see a ghost face here? That's really stupid, but still cool picture. Btw, if you are not yet subscribed to the NASA Earth Observatory you might want. They publish some really cool pictures every week.
