The Dark Dunes Of Erebus Options

[Nirgal]

I've always been fascinated by the dark dune fields of Mars, resembling
in color the sands of, for example, the "black beaches" of Hawai
(inidcating the volcanic/basaltic origin ...)

Here is a colorized view of The dark Dunes of Erebus, as seen by Opporty on Sol 608 (click on image for full resolution (900 KB))

Wonderful image, Nirgal.

I'm looking forward to examining the so-called "Elephant Dune" on the left side of the image. Those dunes are a redder color than the basalt-hematite sands of the ripples and I've seen a couple of instances where light-colored piece of evaporite is high in the dune. I'd suspect these are related to the ejecta blanket of Erebus.
