A mesa in the Avernus Colles region of Mars.
August 25, 2003 - This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows a mesa in the Avernus Colles region of Mars, near °S, °W. The mesa and the very large blocks that have been shed from its slopes are all that remain of a once much more extensive suite of layered rock that used to cover the entire area shown here. This full-resolution ( meters--5 feet--per pixel) image covers an area 3 km ( mi) across. Sunlight illuminates the scene from the left.
