Sand dunes cover much of this terrain, which has large boulders lying on flat areas between the dunes. It is now late winter here in the Southern hemisphere, 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.
