A RAT grind on sol 5027. The RAT is so worn that it is reserved for the highest priority targets, so this one must be quite compelling.

It seems to be a quite friable breccia. Suevite?

These MIs from Sol5033 (right) and Sol5036 (left) form a pretty good X-eye stereo pair.
The fusion is not perfect because there are small differences between the two images, which may be due to dust movements.
[EDIT: Rotated 180 to match Ant's anaglyph. (This puts Sol5033 on the left.)]

New MIs from Sol 5045. Brightened first image, which was in shadow.
[EDIT: Got the left and right eyes reversed on the first image, which was meant to be X-eye. Now corrected. The second image is ||-eye. The dark areas are at holes, not clasts.]

Sol 5057 Navcam panoramic. A nice time to take a pano.
Very nice panorama.
Here is a different version roughly projected into a map to show the 5057 area. Opportunity moved towards the rocks in the bottom left (southwest) corner on sol 5058.

Parallel-eye from Sol 5061.
This is in a pile that appears to have been in the rover path.
The left eye is an L456 composite.

Sol 5066. I wonder what process formed this ring.
Huh. Wonder if the ring is aeolian deposition around a rock made of unusually soft material that weathered away over time.
Vaguely reminiscent of Spirit's "rotten rocks". Water altered rind remaining as the softer interior eroded.
Also reminiscent of this little beauty seen by Curiosity at Dingo Gap on sol 527:

Curiosity has seen quite a few attributed to gas escape (akin to a small mud volcano or diapir) in a sedimentary environment. Finding one here would provide a few insights into Perseverance Valley. Half crippled, sensor limited, operating on a shoestring budget in the shadow of her bigger relation at Gale Crater, Opportunity just keeps on giving.
An outstanding update on Perseverance Valley on the Planetary Society page.

Thanks for that link Serpens. Very enlightening.
The focus on the origin of Perseverance is understandable. The urge to explain this unique feature is what led them to this location. I would hope though that there would also be scope for Opportunity to live up to its name and do some opportunistic science that might have nothing to do with the origin.
In particular, I find the light-toned deposits on dark rocks fascinating. What is the chemistry of these deposits (as separate from the underlying rock)? Is there anything special about the distribution? Has this material blown down from Winnemucca plateau where there seems to be a large reservoir of the stuff? Is the composition essentially the same as the planet-wide wind-blown deposits? Perhaps some of the answers are to be found in the APXS results from the "Aguas Calientes" target. I guess we may have to await the next conference for those revelations.

New MIs. Not so easy to stitch seamlessly.
Here is an overlap 3d slice (X-eye).
[Or maybe ||-eye; it's hard to be sure since the surface is so irregular.]

I wonder whether the same textured, nearby rocks are fragments of the circular rim.

The 3d from my previous post rotated 180 degrees. Easier to interpret as an X-eye.

South Meridiani apparently hosted some of the valley networks that were formed before the Noachian/Hesperian boundary. If the impact that created Endeavour was into an existing fluvial system, I wonder if its location could explain the uniqueness of this section of the crater rim? Of course it would have been altered by subsequent processes but it might have influenced their evolution.

Very nice, Jan - We don't often see panoramas from Opportunity these days. Here is a circular view, lots of tracks visible.

I think the current location is near here, to the left of this crop.

Fun fact.......5083 I was on shift - and not only did we conduct the first NavCam 360 in a single Sol that I've seen in >a year of Ops - but it's in part thanks to a ExoMars TGO pass on which some of these frames came down!
Still trying to sneak in an upper tier to get a proper 360 without a Horizon cut-off. Hard to convince the science team to spend what bits we have on that.

Parallel-eye overlap 3d slices from Sol 5091 MI images, rotated so that illumination is from the top.
(There are additional overlaps, not removed, between top and bottom, so the middle part of each image is seen twice, with slightly different lighting and perspective.)

Parallel-eye. Here it exaggerates the depth perception, which helps show the intricacies of the texture.
