This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a field of secondary craters located on the plains north of Ares Vallis, roughly 30 or 35 kilometers (19-22 miles) northeast of the Mars Pathfinder landing site. These craters did not form directly by individual meteor impacts -- they resulted from the impact of material ejected from a much larger meteor impact that occurred somewhere to the south of the region.
