"dry ice formation is not possible on mars, it require liquid carbon dioxide which need at least 250 psi of pressure but Mars as lower pressure then earth "

mars is also A LOT colder then earth and that temperature difference allows for dry ice to form

Nice try, NASA, but the gullies on Mars finish part way down the slope. You showed that even on a shallow slope the ice went all the way to the bottom.

I would have thought the sand would be more than "a little bit warmer" by about a 100c
