Description: Original Caption Released with Image: 13 April 2006 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows ridges exposed by erosion in the Aeolis region of Mars. The curved and crisscrossing ridges were once channels in a fan of sediment deposited in the Aeolis lowlands. The channels were more resistant to wind erosion than the surrounding materials, so today they are left standing as ridges rather than valleys.
