Starting a new thread as we leave the landing site and start the drive around Seitah. It will probably be quite fast unless something interesting turns up in the ejecta of the craters along the path.
Here is a circular panorama for sol 379, already north of the landing site. Maybe there will be some drive-by shots of the landing site itself. Phil -------------------- ... because the Solar System ain't gonna map itself.

This SuperCam image, like details seen in the Post #39 panorama, shows the downslope flow of what might be a very fine dark dust that seems to originate from the face of the sedimentary layers. For it to overlay the usually ubiquitous brighter airborne dust would seem to indicate a substantial rate of new generation of whatever this dark stuff is. It, again, is reminiscent of what on much larger scales is seen in gullies which raises, again, the question of whether dark downslope flow is purely dust, or is there some H2O involved? Otherwise, it seems like some of the darker rock is eroding at a considerable rate in the present time. Otherwise, how could these dark trails not be covered with the baseline of brighter martian dust?
