Slope streaks are typically caused by the displacement of material, perhaps from a falling rock or bolder, that exposes the darker subsurface to the harsh Martian sunlight. Streaks generally fade over long periods of time. These streaks are notable not only for their wonderful shapes, but their interesting position on the rim of a small and ancient impact crater. This scene is located on the eastern side of a much larger (and older) crater in Arabia Terra.
