This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows house-sized boulders and layered volcanic rock exposed in a pit on the north flank of the giant Tharsis volcano, Ascraeus Mons. The pit most likely formed by collapse. Dust mantles much of the surrounding terrain and the pit floor.
