This VIS image is located in Terra Sabaea. The ridge near the right side of the image contains dark slope streaks. These features are thought to form by downslope movement of material which either reveals the darker rock beneath the dust coating, or creates the darker surface by flow of a volatile just beneath the dust coating.
