This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows dust-mantled layer exposures (left) in east Candor Chasma, one of the troughs of the Valles Marineris system. Erosion of the steeper slope (right) has disrupted the expression of layered material, indicating that some layered materials on Mars may not be recognized as such, depending upon how the materials have been degraded. This image is located near 7.8°S, 65.6°W. The image covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the left.
