Gullies in Crater
Caption:
2 April 2004
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows gullies in the wall of a large southern mid-latitude impact crater located near 39.8°S, 202.0°W. The gullies might have formed by transport of water and sediment down these crater slopes. Alternatively, a fluid other than water may have been involved (e.g., carbon dioxide), but most investigators agree that water is most likely. The image covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the upper left.
