Strange...lights or CO2 ?

    At 1st the brain seen two eyes looking at me and then lights but could it just simply be little pockets of CO2 ice left over before it's totally gone for the summer.... ights.jpg?m Here is the image with auto adjust colours and again but zoomed in
    although it still looks like two eyes with a nose 😃

    That's a martian red devil to be sure. Lots of 'rust' colour. The area to the right of, and below, the 'eyes' seems smoother than other background terrain. Interesting image...

    I think it could definitely be the case that this is an image at the end of the season and that the white bit is carbon dioxide ice left over in say a shadier spot where elsewhere the ice is gone. With Mar's atmosphere so thin and it's atmospheric pressure, you never get liquid carbon dioxide, if it's ice it will sublimate to gas. If it's gas it will freeze to ice. No liquid phase here, though maybe in big craters or cliffs it might be possible for liquid carbon dioxide if the pressure in the rock gets high enough.
