Mars Global Surveyor Mars Orbiter Camera

MGS MOC Release No. MOC2-1065, 18 April 2005




NASA/JPL/Malin Space Science Systems



This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows the results of a small mass movement in a fretted terrain valley in the Coloe Fossae region of Mars (see upper right quarter of the image). The term, mass movement, is usually applied to landslides, although it is unclear in this case whether the landform resulted from a single, catastrophic landslide, or the slow creep of ice-rich debris.
