This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows two barchan dunes in the north polar region of Mars. The orientation of the dunes, with the steep faces pointed toward the southeast (lower right), indicates that the winds responsible for their formation blew from the northwest (upper left). At the time this image was acquired by MOC, the dunes and surrounding plains were covered by seasonal carbon dioxide frost.
