This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows an outcrop of light-toned, layered, sedimentary rock in Aureum Chaos. The darker material, which includes ripples, is composed of windblown sand and granules. This scene is located near 3.8°S, 26.2°W, and covers an area roughly 7.7 km by 3 km (4.8 by 1.9 mi) wide. Sunlight illuminates the terrain from the top/upper right. This southern autumn image was acquired on 14 July 2006.
