...and finally we have also some pseudo-color (L257) of the rover tracks after unstuck:
 I'm intrigued by darker material in the left border of the trench, it appear also different in color ("less brown"); could be simply more recently excavated/collapsed terrain? The left track image quality si poor but it seems to not exhibit this anomaly... -------------------- I always think before posting! - Marco -

I think you're right. Well, the drifts around Oppy's stuck position show layering, especially in places where older drifts appear to be in the process of deflation. Some of those layers are a lot darker than others, and in the color images I've seen, look grayer.
There are a few ways you could get layers of basaltic dust interleaved with layers of evaporite dust and blueberry paving/dust, including deposition during large dust storms and cyclic variations in prevailing wind directions. If the layers in the drifts are from dust storm deposition, these drifts must be dynamic and young features, indeed, since we get major dust storms every few years... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
