Interesting excerpts:

"Faint dust-devil tracks across El Dorado are visible in MOC image R02-00357." - But where?

"Saltating particles: Particles > 80 microns, which move primarily by saltation. Saltating particles are seen to reach rover deck, a meter above the surface." - They talk about bouncing grains?

"... some spherules are surrounded by a later generation cement. This requires multiple episodes of groundwater percolation following sand deposition." - Where are images of this spherules type?

"The volcanic model, however, is simpler and more straightforward, and invokes only processes known to occur widely elsewhere on the planets, and therefore appears to be the more likely explanation for the chemical composition of Meridiani bedrocks" - The Great Meridiani Debate

Which abstract is this in?

I have argued that crusts seen in the MI images at the Opportunity site have the appearance of biological or sedimentary origin:

Subject: Sedimentary films at Opportunity site.

I can't think of any way of producing films or crusts like these other
than through liquid water deposition or biological activity:

You may need to rotate some of these images to properly view positive and negative relief.

And Shaka on this board posted an MI image of Home Plate that showed a similar crust-like deposition:
