In the middle of the image, something that looks a bit like a fossilized leaf.

Circular cavities with dark interiors, bordered by bright material. Single image only---wish there was a stereo pair.

Oops! The old "inverted relief" visual phenomenon where, for example, craters are perceived as hills. This upside-down view makes it easier easier to see the correct relief. The "cavities" are actually protuberances.

This is the context. The MI is about 1/3 from the top and 1/3 from the left. See if you can spot it.

This pair of the MI with a massaged crop of the pancam gives some idea of the coloration (and for some may provide a 3D view).

Interesting textures.

Wafer-like piece sticking up.

Barsoomer;

Nice find! Oppy has imaged such before!

These clusters of basalt rocks keep turning up. They are easy to distinguish by their size, shape, texture and color. They appear to be eroding out of more ordinary cape bedrock. I've not come across an explanation of these. The tight clustering is hard to understand if they are ejecta of the Endeavour event. I think that they were ejecta on the rim of the original Endeavour crater but have been partially eroded, moved, and buried by another larger, distant impact that also created the Meridiani Plains. I wonder how the rover team fits these into the story of Endeavour? They have become more common as Oppy has moved south, and it looks like there are much larger ones ahead, but the proposed route I've seen doesn't visit them.

On UMSF, a post by Fredk mentions that both the exploratorium and the JPL site have not been updating the Oppy images, but they are available in json (a text format with tags that encode a tree structure) format at

http://merpublic.s3.amazonaws.com/oss/merb/images/images_sol4542.json

There are embedded links in the json file to the images.
It is possible to get a plugin for Chrome that presents the data in a more readable way as discussed in the below link, or the links can be extracted manually by downloading the json file and opening it with a text editor.

Yes, there are no Oppy images on the Exploratorium site more recent than Oct 24, and there's no explanation as to why. The JPL and Midnight Planets sites seem to be almost up to date, but I'm not sure about the last few sols. I hope this doesn't amount to a problem. If the Opportunity images are going to be available in a less accessible way, the Midnight Planets site might make them more accessible again. Midnight Planets has made all the rover images more easily accessible than either JPL or the Exploratorium.

Lots of green on the ground here. Might be blue dust over yellow rock, perhaps. (Naw, it couldn't be....! )

A straight combination of L2-L5-L7 seems to make the deck look green now. Not sure if this is real.

And what is that dark blob at the middle of the top of the screen?

A very sharp shadow cast by object on deck in abnormally strong light????

Looks like water descended through a marshy area on the hill and ponded in a flat area below.
