Mars Mesas and Troughs

October 2, 2003
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a grouping of mesas created by pitting and erosion of a layered material north of Apollinaris Patera near 1.7°S, 187.0°W. The terrain is mantled by dust and the troughs between the mesas exhibit large, ripple-like, windblown bedforms. The picture covers an area 3 km (1.9 mi) across. Sunlight illuminates the scene from the lower left.
