This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a
field of dark sand dunes in an unnamed crater in the Noachis
Terra/Hellespontus region of Mars. In southern autumn, the skies are
generally clear and the sun comes in at a steep enough angle that martian
dunes look especially striking.
