Here's a quick partial pan of three pancam images from today
(since I had PTGui open on another project)
Attached thumbnail(s)

You were quick ElkGrovDan
  Lots of details on the hills. Quite amazing. -------------------- |

Also, from looking at the Google Mars of the approach to Cape York, the familiar North/South ripples or dunes that we have been driving across for so long look like they are about to dissapear.

Yep, we're coming up to terrain that looks "smudged" from orbit.
Amazing detail in Tribulation now. Here's an L2/R2 average, with (only!) 2x vertical stretch:
And the ID of Solander looks pretty solid now:

No more dunes/ripples...for now at least

Very subtle ripples only... fascinating. The Bernoulli principle of faster airflow operating on the rim of Endeavour, perhaps...

It looks to me like a 140 metre or so drive towards Spirit Point on 2664. Here's my location, with a couple of craters identified:
The lack of N-S ripples really throws you off - but then there are plenty of features on the horizon now to help get your bearings! |

That's about where I put us too. The rock outcrops confirm it when you look at the full resolution HiRISE.

I hope Oppy's solar panels do also know the Bernoulli principle. I hope, that there will be some gust at the crater rim to clean up the solar cells. Oppy deserves it!
-------------------- Need more input ...

I think the small crater at Spirit Point will be their target. There are some large boulders on its rim, that might allow them to sample the rocks that make up Endeavour's Rim

I'm no expert, but I expect the rocks of Endeavour's rim are basaltic. The hydrated sulfates and clays that are the primary objectives of study are not going to be found in those rocks (ejecta from the Spirit Point crater), I expect. Although Spirit got sick and tired of basalt, it would be a real novelty for Opportunity!

No, CRISM data say that's exactly where the clays will be found, and the hydrated sulfates are in the plains at Botany Bay.

But are the clays more likely to be found in weathered rim or in "freshly" ejected rocks from craters on the rim? In other words were the clays formed after the creation of Endeavour crater or was Endeavour crater created in a surface which contained clay before the crater's formation?
