Re: Timing of flows on Mars
I'm aware that MGS scientists have observed before and after images of the "dark streaks" at the same location on Mars. Are you asserting that you have before and after images of the Martian gullies *at the same location* on Mars (not just an image at one location during a Spring season, say, with no gullies and another image at a different location in Winter, say, with gullies)?
