SkildringChain of Pits on Pavonis Mons.gif	Original caption Pavonis Mons is the middle of the three large Tharsis Montes volcanoes in the martian western hemisphere. Located on the equator at about 113°W longitude, Pavonis Mons stands as much as 7 kilometers (4 miles) above the surrounding plain. The Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) recently spied the above chain of elliptical pits on the lower east flank of Pavonis Mons. The picture covers an area 3 kilometers (1.9 miles) wide by 3.4 kilometers (2.1 miles) in length. The pits are aligned down the center of a 485 meters-(530 yards)-wide, shallow trough. The straight trough and the pits were both formed by collapse associated with faulting. The scarp on each side of the trough is a fault line--troughs of this type are known to geologists as graben. Such features are typically formed when the ground is being moved apart by tectonic forces, or when the ground is uplifted by molten rock injected into the near sub-surface from deeper underground. Both processes may be contributing to the features seen on Pavonis Mons. The pits follow the trend of these faults, and indicate the locus of collapse. Illumination is from the upper left in this image.
