HiRISE: Frosty alcoves on Kaiser Crater dunes
Kaiser Crater hosts a large field of sand dunes. Every winter the dunes are covered with a layer of seasonal carbon dioxide ice (dry ice). In early spring the ice begins to sublimate (going directly from solid ice to gas). … Continue reading

HiRISE: North polar gypsum dunes
These sand dunes are a type of aeolian bedform and partly encircle the Martian North Pole in a region called Olympia Undae. Unlike most of the sand dunes on Mars that are made of the volcanic rock basalt, these are … Continue reading
