This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a 1.5 meters per pixel (~5 ft/pixel) view of the interior of a trough, formed by faulting, on the lower southwest flank of Biblis Patera, a volcano in the Tharsis region of Mars. Boulders tend to be most common in volcanic regions, attesting to the hardness of the volcanic rock. In this case, the boulders and surrounding terrain have been largely mantled with dust.
