Description
30 June 2006
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows dunes in the north polar region of Mars. In this springtime view, the dunes are largely covered by frozen carbon dioxide that was deposited during the winter months in the northern hemisphere. Dark spots indicate areas where the frost has begun to either sublime away, acquire a roughened texture, or both.
