PIA05795: Pit Chain on Olympus


Pit Chain on Olympus

Caption:

21 April 2004
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a chain of collapse pits on the lower northeast flank of the large martian volcano, Olympus Mons. For these to have formed, something in the subsurface must have been removed or changed volume, such as cooling lava within a subsurface lava tube or extension of the crust by faulting. These pits are located near 20.6°N, 129.4°W. The picture covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the lower left.
