About
In this region of the Olympus Mons aureole, located to the SW of the volcano, the surface has been eroded by the wind into linear landforms called yardangs. These ridges generally point in direction of the prevailing winds that carved them, in this case winds from the southeast. Yardangs typically occur on surfaces that are easily erodable, such as wind-blown dust or volcanic ash. The northeast - southwest trending ridges and valleys in the northwest corner of the image are typical of the Olympus Mons aureole. The varying concentration and shape of the yardangs in this area may be controlled by the motion of winds around these topographic features.
