Mosaic sol 1408
WOW ! Thanks a lot eliBonora for sharing this nice work of yours !
yes nice treatment! the parellel slightly exceeds my interpupilary distance on my monitor, making that one challenging but i am finding that its indeed possible to train the eyes to diverge unnaturally. Here are a crosseye and anaglyph of the brushing (09 CCW rotated).

It looks like we may be heading into those boulders next, according to Crumpler's blog.
..Crumpler curiously calls them "dark float rocks", or perhaps that's just a parcel of geologic nomenclature.. i'm inferring they haven't yet definitively spotted smectite from pancam data and are relying on low res orbital data and best hunches to pick the prospective targets to get a profile.. here's Larry's rendering in native resolution:
"Float" is a term for rocks that have broken from their source rock, so they're no longer in place; they lack context (except that they probably originated upslope). Geologists prefer to analyze bedrock rather than float when they can, but the rovers are often forced to look at float rocks rather than outcrop higher up because of terrain trafficability issues. What they do try to do is find float that hasn't traveled far, where you can see the scar that it left behind on the outcrop so you be reasonably sure you know its initial position and orientation.
I was surprised to see that the area of smectite detection by CRISM shown in Crumpler's blog encompasses the floor of the valley almost to the exclusion of the bordering layers of bedrock. But maybe the resolution is such that a distinction cannot be made and the outline around the valley floor is misleading if taken as a hard fact.
Larry Crumpler's field reports are always very informative but this one excels in the amount of information in the illustrations. We even have the angles of dip in the foliations within the rocks in view. Foliation, if I'm not msitaken, is a word for layers in rocks where it seems unlikely that they're sedimentary layers.
Opportunity is still alive and exploring Marathon Valley. Seems like UMSF has sort of ignored her for the past two weeks.

there are some interesting MI images coming down tosol having apparent views of left right and left right, that when rotated 90CW work as stereo

Just been catching up on what Oppy was up to while I was on holiday. Here is the view of the Northwest wall from a week or two back.
From above, Sols 4132,34,37,38 but extended left a bit. Not the greatest quality, but heh!!

Mosaic looking downhill at the floor of Marathon Valley from 4140:
A great look across Endeavour Crater which just about overlaps with the mosaic of Marathon Valley floor from a couple of sols back.
This is part of the valley floor mosaic I'm working on. Control is from HiRISE, details from reprojected panoramas. You get a sense of the complicated patterns in the bedrock here. This covers all the recent activities over sols 4081-4152.

This is a circular view - a bit distorted by the slope and my efforts to overcome that - of Jan's pan from sols 4147-4149. The pattern of outcrops shows up quite well.

That's a shame, those ten posts were filling in a three day image gap ! 
ok then, heres something new: sol4175 MIs have just enough overlap to do a parellel stereo

Thanks so much for sharing this nice work with us
Opportunity moved on sol 4200. Notice the shadow of the rim on the crater floor on this image.
Yes! I don't remember seeing a shadow before. Maybe there have been images which I just overlooked.

There was sol 2847 with some lovely views such as this one, which shows an "opposition surge" at the anti-solar point:
http://mars.nasa.gov/mer/gallery/all/1/p/2...43P2445L2M1.JPG
There were some lovely colour mosaics made, see the old thread starting around here.
I agree the new 4200 navcams are stunning. And I suspect we can see the opposition surge again in this frame:
http://mars.nasa.gov/mer/gallery/all/1/n/4...OZP1685R0M1.JPG
though someone should check the azimuths.

i really liked the ones in shadow from sol4200 but sol4201 are even better. ICE chokes horribly on the righthand R image for some reason, so here's anaglyph of the other two pairs

"opposition surge", so thats what its called, thanks.. i've noticed this interesting effect quite a bit carpooling when one can actually get a chance to stare at at landscapes on low-angle sunny mornings, its especially apparent in iceplant type vegetation, i thought the effect aside from shadow hiding was just a prismatic reflection in plant epidermal cells but perhaps thats implicit as an aspect of the wiki's very brief coherent backscatter explanation.

Speaking of shadows, note the one on the left here.
