25 June 2004 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a series of pits running down the center of a broad, shallow trough called a graben. On Mars, many such troughs, and attendant pits, are the result of geologic forces that extended the crust as the Tharsis region of Mars bulged outward to form what is known as, well, the Tharsis Bulge. This graben and pit chain are located near the Rhabon Valles around 23.8°N, 92.3°W. The image covers an area about 3 km (1.9 mi) wide; sunlight illuminates the scene from the lower left.
