Mars Global Surveyor Mars Orbiter Camera

MGS MOC Release No. MOC2-1126, 18 June 2005

NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a 1.5 meters per pixel view of gullies formed in material on the walls of an impact crater in the martian southern hemisphere. A liquid, laden with debris, poured down these slopes to form the gullies. Gully erosion cut through a thick mantle that covers the original crater wall, and then cut into the old wall itself. The source of the liquid might have been within the layered material exposed in the crater walls.
