Caption:
MGS MOC Release No. MOC2-383, 6 June 2003
Small ridges known as yardangs in the upper left quarter of this April 2003 Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image indicate that wind has stripped away a mantling layer of sediment to reveal the terrain beneath. Layers and boulders on the cliff face near the south-center of the image show that the substrate is quite competent; its location southwest of Olympus Mons near Gordii Dorsum suggests the bedrock here may include old lava flows. The picture is located near 4.8°N, 142.7°W. Sunlight illuminates the scene from the left/lower left.
