Ascraeus Mons Pits
September 13, 2003
This August 2003 Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a suite of collapse pits on the northeast flank of the volcano, Ascraeus Mons. These pits are aligned along the trend of faults that are not well exposed at the surface; the faults are concentric to the volcano summit. The image is located near 13.0°N, 103.2°W. This picture covers an area 3 km (1.9 mi) across and is illuminated by sunlight from the lower left.
