Yardangs in Aeolis

Feb. 4, 2005
NASA's Mars Global Surveyor shows yardangs in the Aeolis region of Mars, formed by wind erosion, and large ripples formed in wind by deposition of sediment.

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows yardangs, formed by wind erosion, and large ripples formed in wind by deposition of sediment. The sharp yardang ridges trend from northwest toward southeast (upper left to lower right), while the ripple crests are nearly perpendicular to this trend.
