Frosted Dunes on Mars
Sand dunes cover much of this terrain, which has large boulders lying on flat areas between the dunes. It is late winter in the southern hemisphere of Mars, and these dunes are just getting enough sunlight to start defrosting their seasonal cover of carbon dioxide. Spots form where pressurized carbon dioxide gas escapes to the surface.
