This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows the layered rocks and boulders exposed on the wall of a trough in the Terra Sirenum region. The layers that erode to produce large boulders are harder and more resistant to weathering and erosion than those that do not. The slope is located near 25.8°S, 139.8°W. The image covers an area 3 km (1.9 mi) wide and is illuminated by sunlight from the upper left.
