Well, we have 3, count em, 3 pictures of Opportunity from HiRISE, and they've made little movie out of them. See this link below:

Also very notable is:

While some of the cliffs around the crater are in fact vertical, the slopes below the cliffs are no steeper than 30 degrees.

I think you all know what that means;-)

I think that has been pretty clear from not long after Oppy arrived, several of us have been analyzing the slopes, MRO isn't the only spacecraft looking at this crater.

I think you all know what that means;-)

No not really.

30 degrees is pretty steep if the surface is loose. Luckily it looks like there are places where the slope is a lot less than 30 so we'll see, should be OK imho. I think the critical issue is going to be finding assessable outcrops, going up to the base of these cliffs is likely to be steep and slippery with many areas ruled out due to shade and inclination requirements.
