This false-colour image shows gully channels in a crater in the southern highlands of Mars. The gullies emanate from cliffs near the crater's rim. They meander and exhibit the braided patterns typical of water-carved channels. When Nasa released this image in 2007, it was taken as evidence that water once flowed on Mars.



Comments
The original Viking pictures of the Cydonia complex were low-resolution. Better images were obtained by Mars Global Surveyor, and NASA made sure to release them immediately to address claims they they might have been doctored. Also, are the Europeans meant to be in on this conspiracy too, via the Mars Express probe?
Great pics by the way!
some amazing geological patterns..
