Sand or Snow? Rocks or Icebergs?

These things have been noticed in many Mars photos for some time, but they can analyse it because what we see on those photos is how things are after that something flowed on those places, as far as I know there isn't any photo of it happening (but I don't know if there would be a way of knowing that it was happening at the time).
I have noticed that on some photos it looks like those liquid flows come from the joining between the present day surface and what looks like a different ground layer, like if something was covered by the dust we see today.
I will try to find one of those photos.
PS: Imagir, use only the [img] tags, that way the image will have a scroll-bar and will not mess-up the page layout.
