Do my eyes deceive me, or is there a dearth of central pit craters on Ceres?

The latest image has a nice perspective that shows some topography:

and of course, a nice view of a bright crater:

Also some dome-like structures visible in other places?

The other white-spot crater looks quite messy, but in a good way:

(Cropped image 2x, not resampled.)

It does looks like the impact scored a direct hit on an isolated pocket of the white stuff.

That is the row of three mountains seen earlier. A map of the general area (thanks, Greenish for the map):

FYI, the released TIFS have much better detail than the JPGs.

That mound just seems to have no rhyme or reason. If anything, it resembles a volcanic dome ( https://en.wikipedia.org/wiki/Lava_dome ).

shield volcano is the word that comes to mind when I see that thing. I wonder how old it is (whatever it is); there are hints of what could be craters on its slopes.

The square arrangement of features is interesting.

Same but with a wider perspective: https://twitter.com/nasa_dawn/status/611222468942934017

The images at full resolution are as usual found at the Photjournal and the Dawn website. The Twitter account rarely provides anything unique other than some extra image description (like characterising the bright crater (spot 1) in yesterday's images as young) and status updates.

Are we sure that volcano-looking feature isn't a crater? Sometimes it's hard to tell if something is a mound or a hollow.

Definitely a mountain.

Perhaps a tip of rocky core poking out through a globe of dust?
