This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows the floor and walls of a small portion of Nirgal Vallis. The floor is covered by large windblown ripples. The valley wall near the center right exhibits a group of gullies, formed perhaps by a combination of mass movement and possibly seepage and runoff of groundwater.
