I think all the blueberries inside are interesting too.

Good catch. Those possibly are berries.

...and, what are those stalactitic-looking thingies hanging on the upper left? Could they be dust dendrites, or are they some kind of unusual erosional remnants?

There are also noticeable holes and indentations.

Another preview of the Greeley pan. I haven't done any individual image color correction yet, any color correction that has been done sofar, has been color equalization in the stitching program itself.

James, very nice work !
The circular version makes me wish I had a horizontal wheel on my mouse to make it spinaround.

Really like your projection; comes close to preserving scale near the rover.

What projection did you use?

Stooke's bogus-malogus projection.

(maybe you could think of it as being something like a stereographic projection)

Or putting it on the blade of a circular saw or table saw. wink.gif

Looks like the sundial gnomon has acquired an indentation. Did Oppy wander onto a firing range? laugh.gif

Right in the middle of the dark patch.

Oh, I see it. It doesn't seem to show up in 3D, though the resolution is pretty bad at this size.

The 'indentation' is an artifact of the highly reflective nature of some newly deposited (or removed) dust, the filters used, and the Sun angle. (That right eye is full of geology filters, mostly IR)
Here is zoomed dial on that sol in RGB

besides, a 'real' ding that big would be accompanied by a super cleaning event (or a nearby meteorite slam)

This link to one of Holger Isenberg's automated pancam composites shows some seemingly scoured-out areas between the pebbles.

http://areo.info/mer/opportunity/2861/1P38..._L4L5L5L5L6.jpg

Given the location, wind action must be the most likely suspect to produce such an effect, along with some visual enhancement of apparent flow patterns by the elongated shadows. That is my best guess anyway, but the way the little gully almost undercuts parts of the surrounding crusty material suggests that it must have been a very very ground-hugging wind. Frankly if I saw this pattern in the Mojave I would be more likely to conclude that a beer-drinking camper (or his horse) had recently visited this place on an urgent errand. Someone get me off the hook here.

I updated the Greeley pan with more images taken closer to the rover.
