I leave my marathon of creation of all spirit's pano for my HiRouteMap to make small pan of sol 1032

Wow...that is one of the most spectacular pans yet. Great work!

congratulations ! very well done ... perfect stitching and impressive atmospheric feel with the extended sky

These remind me of a feature in Endurance Crater. Could this be a "bathtub ring"

Mister Indian3000, that was beautiful. I think you have managed to capture technical perfection and lovely artistic impression in the same grayscale image. I love it.
It could well be one appearance of it, but don't think of the BTR as a chiseled line in the rock. If I have the model correctly imagined, it is more like the average highest reach of the the ancient water table. If the groundwater did not dwell for long above a certain level, there will probably not be very many concretions formed there. Probably at the same time the concretions are forming in the ground water saturated environment, other minerals may be dissolving and precipitating elsewhere, creating other changes in the textures of the rock. If the water remains near a level long enough, it can leave an imprint of its presence. But other processes can create an abrupt change such as the one you pointed out. That seems to be a contact worthy of further study.

The geochemistry of iron during the formative years of the planets has long been been one of my favorite subjects. That element seems to have been quite abundant on/in the inner planets at the same time certain planets' atmospheres evolved from chemically reducing environments to more oxidizing ones, thus changing the chemical behavior of iron. Seeing such apparently ancient rocks with clues to that story, delivered to us by a space-faring robot created by our species, leaves me speechless...

Endurance?

I wondered that too, but it looks like the image is off to the west, about -79 degrees az. I reckon it's just capturing the after-sunset sky glow.

So, in color, it gave us that :

FWIW, new pics on the exploratorium after driving on sol 1034.
It looks like a small move, few meters I would guess. Perhaps the rover is positioning itself for a Christmas IDD campaing and/or get some long-baseline info from Bottomless Bay.

Six image mosaic from sol 1034

Nice one, alan. I loved the view of the tracks in that direction. The largest block in the ejecta layer on the left right side looks eerily familiar to me.

Here is the panorama in the drive direction. I think this provides the first good view of one of the north side dark streaks. What do you people think? I can't imagine what else it could be.

I wasn't expecting them to have quite as much contrast. I wonder if we'll be able to finally settle the discussions regarding whether they are light dust removal or dark dust deposition features when we get closer views.

This really shows that there is a difference in the amount of dust on the North side faces as opposed to the South side faces. If we only have one shot to pick a place for Opportunity to examine, that's a big clue.

Gotta love those tracks.

It's interesting that while, according to the drive maps, we crossed over a faint dark streak at the head of Bottomless Bay between Sol 1027 and 1028, there has been no mention of pausing to look at the streak then.

If this seems an important question, it suggests that Opportunity will continue her circuit of Victoria at least until she reaches the really dark north streaks (around bay C5 and D2 in the unofficial nomenclature).

Yeah very nice composition!

And also (gotta lov...) your perfectly stitched mosaics!
