There was also a mid-drive Navcam 360 on the 3008 drive.

Doug's mid-drive panorama in circular format. There is an offset at about the 1:00 position in this image which affects the horizon, but otherwise it looks good.

Charborob - very nice. Those rounded hills would be the Cromalt Hills, about 300 m north of the rover when the images were taken.

Jan - very nice too. Here is a circular version. The Cromalt Hills are at the 11 0'clock position.

Looks like I have found where I can find the rover drive elevations that matches the elevations shown on the 1 meter contour lines that we used to get in the inset of the traverse maps that are sadly no longer being published. These can be found on a file called 'Rover Path.geojson' that can be downloaded from the interactive 'Where is the Rover' location map. It's a lengthy text file that shows the entire path from landing of the rover with breaks at the waypoints until the most recent sol at the end. It appears to provide Planetocentric longitude and latitude to 6 decimal places, as well as elevation in meters. It shows the elevation at the start of the drive, all the major changes in direction along the path and and the elevation at the end of the drive.
Here is the data for the Sol 3011 drive:-

longitude, latitude, elevation (m)
[137.401164,-4.733507,-4083.785149] beginning of drive (Sol 3011)
[137.401187,-4.733513,-4083.649829]
[137.401186,-4.733512,-4083.663368]
[137.401256,-4.733444,-4083.587848]
[137.401361,-4.733354,-4083.858619]
[137.401543,-4.733399,-4083.471174]
[137.401612,-4.733421,-4083.353024]
[137.401722,-4.733464,-4082.510595]
[137.401895,-4.733549,-4081.218448]end-of-drive (Sol 3011)

I compared the elevations on a selection of a few end-of-drive locations that were recorded on the 'archived' traverse maps, and there appeared to be a perfect match for the elevation values annotated adjacent to each of the contour lines on the old traverse maps.

I've been trawling through the SPICE/NAIF kernels to try and find a match to this elevation, sadly without any success so far. I can only find values that are out of step with those in the "Rover Path.Geojason" file, often by many 10's of meters. I believe that is because of the different ways of calculating the rovers location/elevation.

Still digging... Lots more to read...

Sol 3013 drive, roughly assembled R-NavCam partial pan, that way help to provide a clue or two regarding the location until the updated SPICE NAIF files come down.
It's not much, but it's the best MS Ice could do with the few raw images.

Looks like I have found where I can find the rover drive elevations that matches the elevations shown on the 1 meter contour lines that we used to get in the inset of the traverse maps that are sadly no longer being published. ...

Been following along and this is the info I needed! Was able to finish putting together a basic 1m contour traverse map that seems to match the old ones... manually added contour labels and no coordinates shown but I think the data is right since I used the PDS basemap and DEM per the SIS that @mcaplinger pointed us to.

Here's hoping it's of use in easing your pain:

Note that there is a small "seam" in the DEM that causes the vertical row of jagged contours just east of sol 3011 position. Will be interesting to see if there is any adjustment in the data as they've passed it.

(I'm not a regular GIS user so please sanity check me - this snip near sol 2933 should match the inset from the traverse map here. If so, any future ones or updates will go in the map thread.)
