This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows steep slopes of light-toned rock and dark windblown sand in eastern Candor Chasma, part of the vast Valles Marineris trough system. The rock is probably sedimentary. In a few places, rock has broken down and slid downslope to create a narrow chute and a pile of talus where the slope meets the adjacent dark, dune-covered plain. This image is located near 7.8°S, 64.9°W. The picture covers an area about 3 km (1.9 mi) wide. Sunlight illuminates the scene from the upper left.
