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.
