Paul kindly let me use his assembled Navcams for a mosaic which let me produce this circular view for sol 437, saving me quite a bit of time. Thanks, Paul!

2 of the 5 end-of-drive 4-tile NavCams after the sol 441 drive to site 25/0000, map not yet updated, but it looks like a drive to the north (beyond the large ripples) and then westwards in the direction of Hawksbill Gap

I have assembled one further 4-tile NavCam, but the remaining end-of drive NavCam's currently have a number of missing tiles or suffer from some data drop out. Hopefully those issues will be addressed in the next downlink.

layers are 3 per cleat space or 3.7 cm

This circular panorama was compiled using Paul's Navcam images. Thanks, Paul! It wasn't easy to get them to fit together because quite a lot of the horizon is missing, but it worked in the end. Uphill a bit and then a left turn.

On Sol 441 one of the wheels uncovered the ocher/terracota-colored layer under the thin 'common dust' stratum and (crushed? / smashed? / smeared?) it. What substance can this layer consist of?

Looks like a short drive to the West on Sol 448:

EDIT: I've editted the description as this was aquired during a pause mid-drive.

The drive continued further to the west, but the post drive images are incomplete at the time of this post

This is from earlier in the mission but I didn't want to bury it in an old thread, so I hope you will forgive me for posting it here.

I have been going through the Analysts Notebook in PDS, collecting the uplink and downlink reports and trying to condense them into a reasonable narrative. This is for sols 1-178 only but more will follow.

It is not complete and needs editing - it still has some little notes to myself to look something up, and I am aware it is repetitive and not very exciting (it's not a novel, after all). But I post it here in case anyone finds it useful. It is just a plain text file.

(PS you have no idea how time-consuming this is)

The drive on sol 448 had at least two stops for imaging. Here's one of the end-of-drive NavCams roughly merged with two later images that included a little more of the horizon that was missed due to the >10 degree roll of the rover, hopefully using those additional tiles might assist Phil to compile the polar view

This is the sol 448 panorama in circular form, made using Paul's Navcams. The addition of part of the horizon was very helpful.

Well, that was a tricky one but I managed to put Paul's images together (he let me have a full set) - thanks, Paul. Here is the sol 449 circular panorama. It was a small move to put a tasty rock in the workspace.

I think this is one of the most beautiful outcrops with a cross bedding seen by Perseverance.
This is a slice of the panorama taken on sol 451.

Looking at the horizontal layers in Post #136 (beautiful work, tau!) I wonder if this would mechanically allow a sample that grabs many layers in one tube, and imagine the science that could be performed on Earth, analyzing the differences from one layer to the next, potentially developing an account for how the local (planetary?) environment evolved from one specific martian year (?) to the next at some time in the remote past. It would be curiously specific in relative time, where we'd speak of Year Y, Y+1, etc., without ever knowing precisely when Y was.

This is incredible stuff in these pictures.

Tau, nice (apparent) grainsize distribution on these micro-images. They suggest higher stream load capacity and variability.

Meanwhile, sol 453 Mastcam-Z context images for the sol 453 SuperCam RMI mosaic in the previous post have arrived.
Here are left eye filter 0 RGB context with SuperCam inset, and multispectral filters 1 to 6 principal components.

2. Left eye multispectral filters 1 to 6 principal components
3. Right eye infrared multispectral filters 1 to 6 principal components (unfortunately with strong filter flatfield inhomogeneities)
The pebble at pixel 190 from the left and 430 from the top looks unremarkably gray in image 2, but intensely blue in infrared image 3.

This is a circular view made from a full set of Paul's images from sol 455. Moving uphill. It's interesting that the rocky surface we are sitting on is so much less apparent from the surface than in the HiRISE images. Thanks, Paul, much appreciated.
