Endless sand with few distinguishing landmarks or details, it’s interesting to see very few dunes, mostly a few ripples around the rock. So smooth looking but probably very deceptive. Even so I can imagine a rover in this basin taking years to cross without photographing a single rock.

Looking at the larger picture in the original link, I can see the hard pan base rock where the sand has blown away showing a few old Craters in the lower left. It appears the dune rises a 1000 feet? into the air before it dips down again at the rock. Another feature that would seem overwhelming if you were to see it in person because of its size.
