Crumbled Mesa

Aug. 27, 2003
NASA's Mars Global Surveyor shows a mesa in the Avernus Colles region of Mars. The mesa and very large blocks that have been shed from its slopes are evident.

MGS MOC Release No. MOC2-463, 25 August 2003

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows a mesa in the Avernus Colles region of Mars, near 3.9°S, 190.8°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 (1.5 meters--5 feet--per pixel) image covers an area 3 km (1.9 mi) across. Sunlight illuminates the scene from the left.
