Wind Erosion

Today's VIS image shows a region of wind etched materials near the margin of Lucus Planum. In regions of poorly cemented surface materials it is possible to create large features due to just the action of the wind. The equatorial region between Olympus Mons and Apollinaris Mons is dominated by wind etched regions. The direction of the wind aligns with the ridges and valleys. The dominant wind direction in this region is southwest to northeast; however, other wind directions can occur within a localized region.
