Poof that the micro-dune material in my anomaly image is not atmospheric dust.

Analysis of visible data from the Opportunity rover, 9-20-2007.

In area I: This is atmospheric dust. We know that because it was deposited during the most recent global dust storm. Note the characteristics of this material. It clings to raised surface features in lint like pattern

In area II. It collects on the windward side of the trough. Like good dust should.

We can now know for sure that we are not looking at atmospheric dust in the other image.
