Re: LOOK º¿º
Martians!? The dunes in the dry river beds is most likely from water, not wayward gusty winds or Martians at play. There was clearly lots of water on Mars at one time. Try to look at this objectively and be a good observer of what you see. If you draw forward conclusions it will foster a distorted view. For example if one doesn't believe water flowed on Mars then those dunes must have been made by wind. After all what else could it be. There is no sign of winds in the deep caverns especially with sharply defined borders as in the "Tubes on Mars" pics. If so there would be massive wind erosion up on the surface. I just don't see that.
