Exhumed Crater with Slope Streaks

December 15, 2003
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a crater in Arabia Terra that has been exhumed. The picture was acquired less than 1 week ago, on 9 December 2003. The crater was buried beneath layered material, but erosion later brought it back to the surface. A thick blanket of dust mantles the scene; dark streaks have formed as some of this dust slid down the crater walls. Old, dust-covered ripples of windblown sediment occur on the floor of the exhumed crater. The image is located near 20.9°N, 320.7°W, and covers an area 3 km (1.9 mi) wide; sunlight illuminates the scene from the lower left.
