Just a guess, though.
It was obviously compressed in the APOD pic. It’s the darkness and it sitting in the middle of what looks like relatively solid terrain that truck me as odd. Like someone dumped a large load of sand there.
But that’s what’s fun about seeing images from the other planets. One surprise after another.
That looks like Colorado’s Great Sand Dunes.
Yep. Mine tailings, but by whom!
