This observation was a public suggestion using HiWish from a class studying Mars: there are several channels nearby a ridge region. These channels lead from the region towards a crater that has an irregular rim. Possible fluvial processes occurred at this area. Dunes with thin crests line the channel floor and are oriented in the same direction.
