In some recent mars orbiter photos is some very intriging photos. In these photos is what appears on dunes at the seashore beach grass or a form of bush. In the attached photos taken at 300 meters resolution is what undoubtly looks like beach dunes on earth. I would love to see someone do a lander site in the mist of these dunes. If you have ever flown over beach dunes somewhere or seen bushes in a aroyo here on earth these look the same. Here on earth grasses are growing in some of the most hostil conditions on earth.

*I think I -might- know what you are referring to: Sand dunes unthawing with the approach of the Marsian spring season show a darker color...which does look like bushes. I'll see if I can't dig up a photo and we can compare if this is what you are referring to.

Well, I checked through the Archives of "Astronomy Picture of the Day", to see if it were they who had run the photo I have in mind. I used their Search feature, using the words "dune", "thaw" and "unthaw"...I got results, but not the photo I was looking for.
I've visited the link above previously, months ago. It may be in there; however, a cursory hunt on my part didn't yield the photo -- you may wish to dig through it further.
I'm very busy with relatives arriving on Sunday, am wrapping up my work week, etc., etc., but I'll do what I can to keep looking throughout my work day today (I'm on the computer anyway) and will check back at the message board.
Meanwhile: Google.

*Found it with Google "Images" search, "Mars dunes."
Is this what you are referring to?
