Why do you think this is important, O'brien? I am curious. I am almost certain you know the importance of this, given your other topics. I can't believe it has taken so long for me to notice this.
I also notice the fracturing of the stone on the surface. That's present in a lot of places. I am not surprised.

Barchan and all these other kinds of dunes... Mars has gotten the wrong name. Regarding the kind of surface brought to us by so many images its correct name is Dune, the desert planet.

The wasted land. No hills, nothing, just a flat country covered by tiny flat "dunes". Much more interesting than the "dunes" is the pretty flat ground. Some sort of fractured floor, fractured into nice (fractale ? )geometric patterns. A mosaic, probably going to the horizon.
