This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows light-toned, layered outcrops of sedimentary rock exposed at the top of a small mesa in northern west Candor Chasma of the Valles Marineris trough system. Large, dark, windblown ripples cover the plains surrounding the mesa. These features are located near 5.4°S, 74.6°W. The image covers an area approximately 3 km (1.9 mi) wide and is illuminated by sunlight from the upper left.
