This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows troughs and a pit, possibly formed by collapse, on the volcanic plains south of the large volcano, Ascraeus Mons. Wind-eroded debris mantles the scene and partly fills the depressions. The image is located near 4.5°N, 105.5°W, and covers an area about 3 km (1.9 mi) wide. Sunlight illuminates the scene from the lower left.
