Looking at that image I expect a coyote to come plumetting down on the rover and then an anvil to crash down on both of them.

Good point, though. I have no clue how stable these cliffs are. Come to that, we really don't have much of a clue as to the frequency & intensity of martian seismic events, though IIRC V2 didn't find much at all (V1's seismometer was inop, unless I got that backwards). The motion of Oppy shouldn't be enough to trigger anything by itself, though considering such effects in 0.38g combined with an utterly dry outcrop is kind of difficult...are ancient evaporites all that's holding this thing together besides compression?

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Although, you do have to admit that Acme has a very consistent track record -- and that record is, to be frank, abysmal. Therefore, you'd expect the Acme Mars Lander Wile E. Coyote would have to have used would not have gotten Canis Coyotus safely to the surface, much less anywhere near our beloved Oppy...

I was slightly disappointed yesterday, but I have greater expectations today.

I am really impressed by both stu's and james canvin's views of the strata exposed on the face of Capo Verde. For the first time details can be seen in the shadows. Now the geologists can get to work describing these beds which I think are stratigraphically below the Gibson band that Oppy RATed a few months ago. Am I correct in thinking that I can see lenticular bedding or am I just imagining it? Am I correct in thinking that some of the rocks on the slope are in situ and are therefore representative of an even lower stratum?

I always think of the Acme Corporation when I see the Maas joke video of the RAT going into the rock and the rover spinning around. "If the Acme Corporation had developed the MERs."

Has there been any attempt to correlate the layers in Victoria to the layers identified in Eagle and Endurance craters? Was there any effort to follow the sequence(s) and surface layers with the APXS and Mossbauer data as Opportunity moved South? As I recall there was some ratting and integrating underfoot throughout the trip and in the exposures in Erebus.

Opportunity's little Mossbauer unit must be pretty tired by now. It has a halflife of 3/4 year (roughly). So now, after about 8 half-lives, activity is down to a few parts per thousand of the initial strength.

There is a path in front of the rover which has a rocky ground almost at the base of the wall. That ground is layered, visible on both nav and pancams, and might be in situ.

... and a bit of the floor, too... lots of rocks Oppy, be careful now...

We have GOT to get a closer look at the jagged rock bottom left on this image...
