8 September 2006
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows light-toned ripples covering the floors of troughs in the Adamas Labyrinthus region of northern Elysium Planitia. The ripple crests generally run perpendicular to the trend of each trough, indicating that the dominant winds involved in shaping these ripples blow up and down, through the troughs, independent of the direction of winds that blow across the plains outside the troughs.
