Sol 3505 ( Dec 3, 2013 ) panorama ( HD format ) of rock outcrop:

Oppy has moved up slope about 30 meters to the next science target.

Planetary Society monthly update of MER mission.

Where there's clay, there could be other interesting stuff.

Looking SE before 25 meter drive:

and view afterwards on sol 3506 ( Dec 4, 2013 ):

The rock outcrop "Great Keppel Island" of reply 181 only merited a 3x1 L257R267 study before the surprise ( to me ) move towards the SE.

What are those inky black areas?

Barsoomer/184: Dark sand dunes.

Re the 'rock tips' in Hort's images, these are wind-eroded clasts/fragments which weather proud with respect to the matrix they sit in.

No problem with Thomas's geology earlier.

Here's a couple of Steve Squyres quotes from the latest Planetary Society Update (linked in Barsoomer's 182, Thanks):

But the outcrop also has "some very strong, erosionally resistant rock clasts that are embedded in the fine-grained, more erodible matrix," noted Squyres. "There's been a lot of wind erosion, and because of a prevailing wind direction. The sand blasting that takes place as the wind blows sand across this outcrop has created a kind of grooved or striated appearance to this thing."
"From a distance it looked like it might be finely layered, but when we got up close we realized it's not layering at all," said Squyres. "What we're seeing are the consequences of wind erosion of very heterogeneous rock."

Wow! Its NOT LAYERING AT ALL. I have to chuckle being in on the joke. The layering in Moreton Island and every other outcrop we've seen since starting the climb is no doubt a Royal Pain in the Ass for those who would like this material to be crater rim eject emplaced by the Endeavour impact. It just doesn't fit.

The rock of Murray Ridge seems to have been changing as Oppy ascends toward holding ever larger inclusions, but now this navcam image makes the rock here look more like the good old fine and bright Meridiani bedrock again. I don't see any layering yet but if I do I'm going to laugh out loud. Why would the Burn's Formation reappear on top of this ridge? Its no problem for the impact sedimentation scenario I've been imagining because that has always included a strong possibility that fine bright surge material had completely buried Endeavour Crater and the raised rim at the end of the event. The landscape we see now has been created by erosion of those sediments and the coarser material (breccia in a matrix) that was generally deposited underneath the fines.

I wouldn't be a bit surprised to see bright finely-layered rock up here but we haven't yet. Maybe that's what the clay signature is, after all the bright rock is thought to contain significant amounts of nontronite.

Oops. Here's that image I should have posted with my 187:

From the TPS and other reports, it seems they were hoping the "Winter Wonderland" would be like the Whitewater Lake area. However, so far, at any rate, it doesn't look there are any newberries around.

Sol 3508 panorama in the next drive direction :

Today ( sol 3512 )is a driving sol and Oppy should be headed towards this area.

Note: My 14 year old tower PC died a few days ago and most of my Mars photo tools are on that machine. So until I have resurrected that machine ( new mother board is on its way here ) I will have to rely on my laptop to process the images.

Not looking promising for new rock types.

Odd content downloaded lately to the Exploratorium, the last 3 days (Dec 8, 9 & 10) from both Oppy's pancam and navcam the images have been identical. This is probably not very interesting.

Yes, it is odd that no new images have been downlinked since sol 3509 - and in a few hours it will be sol 3514:

4. What EDRs did we request?

Expected EDRs by sequence number and image type:

Perhaps there is still some concern about the wheels.

Winter Haven on Murray Ridge just ahead?

STILL no new images posted. There is a problem.

Glad to see the old gal is OK.

Sol 3514 (Dec 12, 2013 ) guestimated position on enhanced difference false color map of Murray Ridge:

My guess is that yellow / green mottled area just to the south east of the current position is the clay signature.

I wonder what the scarlet red areas about 30 meters to the south of the clay are? Maybe a future stop after mucking around in the winter haven clay muds??

****** Note added Dec 21:

This guestimated map position is wrong. See the link in the Flickr image for the correct position - about 30 meters further south. I think I accidently left out a drive when I was calculating the position.

The new mother board is working - but one of my main image editing tools now reports that "the registry has changed. Reinstall the application"! I had to fiddle with the O/S product key during a "repair" of the O/S - so I think that broke the application.

I hate Micro$oft.

Horton, re your 198, Thanks for that guesstimate of where the clay patch may be. Wow, on the face of it what an unlikely location to find a concentration of anything, up on a ridge that's supposed to be the rim (proximal) ejecta of a big impact. I suppose that if there had been a thick layer of clay-bearing material under the future location of Endeavour Crater, then some could end up still together in the rim ejecta. I don't need to consider such an unlikely possibility except as an exercise and argument, because I'm pretty sure that we have not yet examined any outcrop that is rim ejecta from the Endeavour impact.

What does it say about the progress that Mars Science has made up till now, that we're going looking for clay deposits in such an unlikely location? It says we've learned nothing yet. A picture is not forming.
