This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows partially-filled collapse pits on the eastern flank of Alba Patera, a large volcano in northern Tharsis. The three pits near the bottom (south) of the image have collapsed to the point of coalescence, while the northern-most pit remains largely a separate entity.
