This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows dust-mantled troughs formed by faulting on the plains northeast of the volcano, Ascraeus Mons. The smooth areas are covered with thick accumulations of dust, the rougher surfaces are lava flows that also have been blanketed by dust. Thick accumulations of dust are common throughout the Tharsis volcanic region of Mars. This picture is located near 8.3°N, 117.5°W, and covers an area 3 km (1.9 mi) across. Sunlight illuminates the scene from the lower left.
