26 October 2004
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows terrain in northwestern Argyre Planitia during southern autumn in August 2004. Several mesas stand high above a rippled plain. Argyre is a very ancient and heavily modified impact basin. The ripple patterns were probably formed from windblown sediment. This image is located near 47.1°S, 45.6°W. The picture covers an area about 3 km (1.9 mi) wide. Sunlight illuminates the scene from the upper left.
