NASA/JPL/Malin Space Science Systems



This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows two troughs/depressions formed along the trend of the Sirenum Fossae, a suite of very extensive troughs formed by faults that are radial to the giant Tharsis Bulge. As the Tharsis region bulged outward, adjacent terrain expanded and formed a series of long, extensional fault systems.
