The pancams are all taken with the L7 filter which doesnt highlight any outcrop rock. This navcam image is perhaps slightly more revealing:

Wow, the right side of Duck Bay is steep, that isn't the 18 degrees that we measured on the other side!
I'm no expert, but it seems to me that if the prevailing winds come from the south (as the dark streaks on the north suggest) then it makes sense that the exposed south facing rim would be steeper.

The side just touching Cabo Frio, yes.
But look to the ramp just starting at the right side of the image; it seems to be fine and not very steep.

L7 is the normal 'drive dir' pancam filter. They used L2 for a while as it shows outcrop as a better contrast - but spacially, L7 is the sharpest.... one of the Pancam updates with JB tackles this issue in full.

And another thing to consider... the light-toned horizontal bed we see in the L7 Pancams on the far wall has a bluish color, not the reddish L2 IR tone. This suggests to me hematite/blueberries instead of keyserite.
A full filter set will be informative.

If they take Opportunity in, they’ll probably want one of the bays that gets the most direct sun light. That narrows down the choices.

There are a lot of things to consider. The general slope of the bay in question - unless it's more or less sloped in a northerly direction it will negatively impact solar power. The cape walls could be a real problem aswell as they can dramatically affect the amount of direct sunlight that will fall on the panels and that is a particularly troublesome right now with Tau being low. That said Cabo Frio looks likely to be significantly less of a risk than Cabo Verde .

I was interpreting the apparent big hole in the right foreground of your picture posted above as being a slump feature a few metres back from the main rim of Victoria. Might be Cabo Frio itself, but see what you think...
Kenny, if I understand you right you're seeing what jpl is calling Duck Crater. Check out

Perhaps one of our math & image gurus can help give a sense of the scale, maybe put two similar images of Endurance & Victoria crater walls together with Mystery Man standing at the top or bottom. That should give some perspective as to how much vertical relief Vicky is showing us.
Already did it! See

Yes, your interpretation is right. The prevailing winds comes from SouthEast. The wind has originated sand deposition on the South East-South side. The north slope is steeper than the south ones. On the other hand, the north side has more compact surface than the south ones which is more sandy.

After being out on mind-numbingly flat meridiani for sooo long now I'm finding it hard to believe we're actually seeing some topography now! Look at those $%#@& cliffs! LOOK AT THEM!! I honestly was expecting maybe 50-60 degree slopes, but these look past vertical in places!!
Hey Phil and everyone, here's one way to put it: we sure won't have to do any vertical stretching here!

Compare
today's rear hazcam view with
sol 943's. You can see clearly that we've crested a bit of a ridge and have started to drop towards the rim. Almost perfectly smooth here too.

Horton, that's a brilliant way to pull out colour. It never occured to me that we could squeeze colour out of L7 and navcam, but it makes sense. Navcam is broad spectrum, but will be dominated by the red-infrared of typical martian ground, so it complements L7.

These are 110x80 degree perspective views of Endurance and Victoria, respectively. Superficially they look a bit alike, but put them in separate browser windows and flip back and forth, and you may begin to appreciate the size difference.

Thanks Howard, that helps. Because you're right. It seems hard to get a perspective. This crate is so huge that it's hard to really get it on one computer screen. I'm sure that the image wizzards in this forum will make some pretty awesome images. JPL has nothing on them!

Nice comparison! Though it's still hard to appreciate the size difference, because the *angular* extent of the two craters, as seen from a point on the rim, is pretty much the same (nearly 180 degrees). The only way to fully appreciate the size difference is to have objects of similar absolute size to compare in both images. Yes indeed, it sounds like a job for ... Mystery Man!
