The face is now a skull

Mars express has recently taken high resolution shots of the mountain range known as 'The Face' to reveal it looks more like a skull. Freaky stuff. Reminded me of the SS skull from thier skull and crossbones motif for some unknown reason. EEK Nazi Martians... whatever next. Or maybe it's like a giant hazard warning symbol. 'Warning toxic planet' 'suspected carcinogenic properties'.
