This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a chain of collapse pits on a dust-mantled, lava-covered plain northeast of Ascraeus Mons—one of the giant volcanoes located in the Tharsis region of Mars. Pit chains are associated with collapse which may be driven by several processes including, but not limited to, crustal extension owing to tectonic processes and the collapse of the roof of a lava tube.
