Happy to...
When I've more time.
I've only viewed the video once and was enthralled by it. Some of the landforms are unfamiliar to me. I was struck by the beautiful talus cones with possible water streaks, the patterned ground of permafrost, and the weird sublimation forms of the ice cap. If you've any specific forms that caught your eye, let me know with a screen shot or a time stamp and I'll do my best to speculate what we are seeing.
And damn those sand dunes are beautiful!
