MGS MOC Release No. MOC2-435, 28 July 2003

One of the goals of the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) Picture of the Day collection is to provide a sense of the great diversity of terrain, surfaces, patterns, and textures of the martian surface, as viewed by the MOC high resolution (narrow angle) camera. This image shows an intercrater plain in the Memnonia region that has been severely eroded by wind to form sharp ridges known as yardangs. This terrain would be very difficult to walk, or drive a rover, across. The picture is located near 11.8°S, 157.2°W. The scene is illuminated by sunlight from the left.
