This unnamed crater in Terra Cimmeria is not as round in shape as other craters. Major landslides have occurred on the crater rim, resulting in the final shape as seen by NASA's 2001 Mars Odyssey spacecraft.

Olympia Undae is a large field of sand dunes surrounding Mars' North Polar ice cap. High latitude covers them with water and carbon dioxide frost in the winter so they are illuminated. NASA's Mars Reconnaissance Orbiter views these best in summer.

The Martian north polar layered deposits are an ice sheet much like the Greenland ice sheet on the Earth in this image from NASA's Mars Reconnaissance Orbiter. This Martian ice sheet contains many layers that record variations in the Martian climate.

The dunes in this image from NASA's 2001 Mars Odyssey spacecraft are still partial covered in frost. They will get darker and darker as the frost is removed and the underlying dark material is completely exposed.
