Fantastic scenery! Here's a circular view from the 3909 location, from Jan's pan.

smectacular!
Can't wait to see Spirit of St. Louis crater just over that ridge, and a closer look at it's curious lonely 'rock' ... 
Here is the complete Navcam panoramic view taken on Sol 3909 and Sol 3910.

Thanks a lot Jan for this nice panoramic view.
Thanks to it, I can now really feel that we are in a new part of the mission : Cape York is now far away and hidden by Cape Tribulation for good (at least until we reach the next summit...)
Something different: Since yesterday the science article "Ancient Aqueous Environments
at Endeavour Crater, Mars" (from January 2014) is accessible for everyone: http://www.sciencemag.org/content/343/6169/1248097.full.pdf.
(You can register for free to get access this and older science articles. Every article older than one year can be read. I think that's fair.).

Abstract:
"Opportunity has investigated in detail rocks on the rim of the Noachian age Endeavour crater, where
orbital spectral reflectance signatures indicate the presence of Fe +3 -rich smectites. The signatures
are associated with fine-grained, layered rocks containing spherules of diagenetic or impact
origin. The layered rocks are overlain by breccias, and both units are cut by calcium sulfate vein
precipitated from fluids that circulated after the Endeavour impact. Compositional data for fractures
in the layered rocks suggest formation of Al-rich smectites by aqueous leaching. Evidence is
thus preserved for water-rock interactions before and after the impact, with aqueous environment
of slightly acidic to circum-neutral pH that would have been more favorable for prebiotic chemistry
and microorganisms than those recorded by younger sulfate-rich rocks at Meridiani Planum.""

Thanks a lot Jan !
I hope that Oppy will climb close the summit of the rocky outcrops at left to get a global view of Marathon Valley before roving inside it...

Very nice!
Before Opportunity entered Endurance crater, back in the upper Jurassic, and before it entered Victoria, it took stereo images from the rim to help plan the entry and activities. So did Spirit, looking down into the Inner Basin from Husband Hill. So it's quite possible that we will see some stereo imaging of Marathon Valley from a good vantage point - especially its southern side, where north-facing slopes might be needed next winter. Right now we can see down into Endeavour, not into the valley, so it can't be done from the current location.

So, in this area of the rim and into Marathon Valley, are we looking at uptilted rock layers, overturned rock layers (more fragmented), or piled gobs of chunks oriented every which way?
(From the standpoint of the Endeavor impact. That impactor slammed into terrain that was a mix already, but given that.... what part of the crater rim structure are we amidst?)

One thing I'll note -- the craters we're seeing up here on the upper slopes of Tribulation look like they have regular rock ejecta. The craters down on the plains, and in the lower units, had that quick-eroding evaporite that would crack and make the entire crater, rim and ejecta and all, look like it was put together from mosaic pieces. You don't see that in and around the craters up here.
It'll be interesting to see when the craters resume that mosaiced appearance.

Our location is very exciting. Phil's map makes it look like Opportunity may be driving to an overlook ridge to get a great view into Marathon Valley---what a panorama. Phil, on the map thread I think it would be great if you could extend your map 0.2 or 0.3 km to the south and 0.1 or 0.2 km to the east so we can see where we are going... 
I'm preparing a new map base now, but these maps are designed to fit pages in a book, and can't be extended randomly.

While we're waiting, here's Phil's route map dropped onto a crop of Larry Crumpler's map from his blog.

It may be obvious but in case it isn't, we can now see Spirit of St Louis very nicely.

I did a quick circular pan, combining the images from Jan and Charborob, to locate us on sol 3923.

And a quick circular version of the 3926 pan. I'm not convinced we can reach a good viewpoint into the valley. If I had to speculate, I would say we will turn southwest and then southeast again to get to Spirit of St. Louis.

What made Marathon valley? Any ideas?

d'oh! typo in the caption...it's Marathon Valley of course.
Can't wait to see the colour view (hint James)

I posted the left most frame to Twitter last night.

However the next one to the right was missing so I didn't post the rest of the mosaic. I'll see what I can do later now that has been (mostly) filled in.

Some impressive erratics left by the melting of the last glacier covering this region 
Possibly there are other explanations...

Thanks Astro0 and James for the stunning views. For context, here's what we're seeing, comparing the view from higher up at 3906 with an orbital view from GM (not sure why the colour table is messed up). Like-coloured circles are identified:

The spectacular gulley in James's colour view is circled in white and looks surprisingly subtle in the orbital view. It's an offshoot from Marathon Valley proper.
