It's time to start a new thread - this will cover the remaining work in Seitah and the drive back to the landing site.

Sol 265 SuperCam Remote Micro Imager with context images Mastcam-Z sol 241 and Navcam sol 248.
It took me a while to find appropriate context images.

Looks like there may be some ripple structures preserved in the rock in that image.

I see what you are talking about, at some of the bed boundaries. There is also a fallen piece that has a bedding plane exposed with what could be small 3D dunes or ripples (can't quite determine the scale). They both are not pleasingly preserved, at least from here, so we'll have to wait and see. We've been seeing distinct bed boundaries for a while, in several places along the traverse, at several stratigraphic intervals. None of them looked completely planar, but there were no obvious ripple forms either, let alone cross-stratification within the beds. After finally determining that the grain size was in the medium-coarse to granule range, that's not surprising. Maybe the grain size is smaller in these outcrops, and ripples and dunes could have formed during the flows.
