Streamlined Rocky Outcrops near Olympus Mons (Enhanced Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia)

Caption NASA originale:"This MGS-MOC image shows wind-eroded "Streamlined" Rocky Outcrops overlying Lava Flow Surfaces located to the West of Olympus Mons. Outcrops with this appearance are also called Yardangs. Yardangs typically form in Sedimentary Rock or Volcanic Ash that contains some amount of Sand. The weathering of the Rock due to the Aeolian action cause the release of sand-sized particles from the Outcrops and, in time, such a form of erosion slowly shape the rock into the classic, inverted boat hull-like shapes of Yardangs".
