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))

I've seen no remnants of an ejecta blanket, either. Erebus is an ancient and highly eroded crater and we're seeing the bottom of the crater bowl. Although we see tilted strata in places, for the most part it is meridiani-flat. There are many little pieces of a puzzle that are starting to come together.

Glad to see you back, CR.
