PS - only later did I notice that Fredk had posted about this earlier, but he had the misfortune of being stuck on the previous page so I didn't see it at the time.

Amazing. Shooting from the hip, this would appear at first glance to be some sort of evaporite structure like barite 'roses' in terrestrial deserts. Maybe gypsum?

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Here is Jan's sol 3397 panorama in circular form. I hope they can get through that place.

Some fun geology in stereo on sol 3396. Anaglyph:

How wonderful is this? It appears to be a "desert rose", likely a twinned crystal of gypsum (calcium sulfate) grown within a sandy sediment and incorporating some of the sand grains in it's structure. Common in the desert where there are saturated, liberalized waters percolating in porous, Sandy sediments. Note the "surface" it is on is actually a flat plane cutting across many fine layers. Aeolian erosion in action!
These features speak volumes about the processes involved here.

Where do we suppose the desert rose is located on this Pan?

The "rose" was near the 3393 location, so not very visible in the 3397 view.

You can see "roses" in this 3393 ML:

and some context in this hazcam view:

Good. These views, plus the 3393 panorama, give a context of this lithology. I see some fracture fills, which suggests saturated groundwaters.
