Here's a paper, albeit unpublished, asserting that at least transient water is likely to be found on mars:

Richardson, Mark; Mischna, Michael, — December 2004
The Long-Term Evolution of Transient Liquid Water on Mars

I agree, Shaun B. that it looks like the kind of mud you see in a puddle as it dries up, especially such a puddle in the red clay of the state of Georgia, where I grew up. I wonder what would happen if you could take a stick and poke at it. Would it make a scar in the surface like in Georgia mud? Would it ridge up like sand? Or would it puff up into a little cloud and then settle back down into a nice smooth surface again?

If someone could tell me how to upload pictures to this site I can send several more. I can go back to NASA and get the URLs, but it takes a lot of time.

Thanks for your reply. I know the temperature on Mars is far too cold to sustain liquid water for any length of time. But if this is dust it settles remarkably like a liquid. I have a half dozen photos the NAVCAM took in this area that look almost as dramatic as the one at the above URL. With each of these photos if you zoom in on them, the visual effect of liquidity gets stronger. I don't know much about chemistry but is there another liquid other than water that could stay liquid in this kind of cold?

OK, no response yet? I did go back to the Mars site and find one pretty interesting PHOTO! Here's the URL:

It looks even more like water if you can zoom in on it.

I'm a newby and not too adept at computer and internet stuff. But I have been following the Mars rovers pretty closely. In December, when Opportunity was making its way out of Endurance Crater it took photos of rock slabs, several of which had what looked like muddy water around the base. About the same time the NASA Mars site announced the discovery of conditions that would indicate an ancient site of a sea bed - a conclusion derived from geology, not the current presence of ground water.  I have downloaded those photos but I'm not sure how to send them here with a posting. I did not keep the URLs with the photos, only the lengthy NASA/JPL id codes for each one. I would love feedback from an expert on these photos, but never recieved a reply from NASA when I wrote them (Thea ARE a bit busy these days!) I'll be happy to send these photos to this site if someone can tell me how to do it. I have Windows XP. Thanks
