In the winter a layer of carbon dioxide ice (dry ice) covers the north polar sand dunes as shown by NASA's Mars Reconnaissance Orbiter. In the spring the sublimation of the ice (going directly from ice to gas) causes a host of uniquely Martian phenomena.

Setting the Scene for Curiosity's First Drilling

The unnamed crater is filled with a large amount of sand, the surface of which has been sculpted into dune forms. This type of crater fill is common at high latitude. This image is from NASA's 2001 Mars Odyssey spacecraft.
