This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows rugged, wind-eroded material that once used to completely cover the upper flanks of the martian volcano, Apollinaris Patera. This material; perhaps ancient volcanic ash or more recent, cemented dust, has been partially removed by wind erosion, revealing a smoother surface beneath. This view is located near the summit of the volcano, around 9.3°S, 186.1°W. Sunlight illuminates the scene from the upper left.
