This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows the walls and floor of a wide trough in the Sirenum Fossae region near 26.4°S, 140.7°W. Boulders rolled down the trough walls as they eroded out of the rock outcrops exposed on the upper slopes. Sunlight illuminates this scene from the upper left; the image covers an area 3 km (1.9 mi) wide.
