This observation is a re-imaging of small dunes on the north side of an impact crater that we also captured in 2007. Other small changes in the ripples and possible transverse aeolian ridges might be in this location. With a digital terrain model, there is the potential to find long-term changes. This scene is in Tyrrhena Terra.
