NASA's Mars Global Surveyor shows 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.

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.
