MGS MOC Release No. MOC2-347, 1 May 2003
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image of layered sedimentary rock outcrops in northern Sinus Meridiani shows several buttes and ridges formed in rock that is somewhat resistant to erosion. The circular feature near the bottom of the picture is an old impact crater that was filled, then buried within the layered material, then later partially exhumed. The sinuous ridge and small buttes to the right of the exhumed crater are composed of the same rock materials that once buried the crater. The picture covers an area about 3 km (1.9 mi) wide near 2.3°N, 353.6°W. Sunlight illuminates the scene from the left.
