This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a series of small gullies on the north wall of a crater within the much larger Green Crater in Noachis Terra, Mars. The gullies might have formed by seepage and runoff of ground water; others have suggested that melting snow or ice might create such gullies. The crater floor exhibits a field of sand dunes and some wispy, dark streaks left by passing dust devils.
