No "obvious signs of geysers thus far." And yet those mountains in the center keep looking like gigantic versions of ice volcanos on Lake Michigan to me.

I keep thinking of Lake Michigan ice. Just google images for these three words, and for "great lakes" + "ice volcanoes."

It also looks somewhat similar to an aerial view of Old Faithful (minus the public reception area).

I love the side-by-side stereo images. For those of us who know how to view these -- cross your eyes and focus on the image in the middle -- it provides SO much more information about the landscape. Unfortunately, 10-15% of people don't have convergent vision and so can't do that.

Let me go out on a limb on the lonely mountain. If this is an uplifted feature, I've been puzzled by the lack of debris around the base.

Now that I'm looking more carefully, I see relatively fewer small craters around the base to the North and East (12-4 o'clock), especially between the mountain and the crater (12-2 o'clock). There is obvious flow INTO the crater (11 o'clock). And to the Northwest and West, perhaps what looks like a splash or flow (11-9 o'clock).

What if the Northeastern half of the mountain lifted first? The ice (?) interior was exposed as the regolith sloughed off. By this interpretation, the Southwestern quarter of the mountain has uplifted more recently, carrying its cratered surface with it. The regolith has not yet sloughed away. I see no sign of debris flow (yet) there, around the base of the mountain (~9-4 o'clock).

Alternatively, the lonely mountain results from a single uplift event, but for whatever reason the rake of the NE half was steeper -- causing the powdered regolith to slough away there.

If I have my compass bearings right, it's now clear that the North, West and East slopes of the mountain are not only "shiny" but craterless in contrast to the Southern slopes (partly in shadow) and plateau which appear heavily cratered. Presumably young versus old. Along the Western slope there is a circumferential discontinuity about halfway down, broken by a thick ridge that appears to have a splash of debris at the bottom. There appear to be two or three bright spots on the plateau, far from the slopes, and one partway down the cratered slope on the Eastern side.

I can't wait to read speculation on all this. What's going on?

A maximum resolution gif. Not the individual frames (I can pull those myself).

Does anyone have, or know a link to, a gif version of the rotating Ceres topographical globe animation? I have searched the internet without success.

Beautiful!

The "barnacle mountain" at the bottom-far-right looks a bit like what we're seeing in the most recent Pluto high rez image.

Apollo 17 landed in this valley. Does anyone know if that bottom-right mountain is an old volcano?

This seems unlikely to me. These "barnacle mountains" (I love the term) each have a pit at the top.

As I noted earlier, the first thing that jumped out at me from the new image is that there is a pit near the peak of many of these mountains. Are these volcanic craters?

Each of the 10 mountains in the lower third of this new image, protruding from the Tombaugh Regio flats, has a dark crevasse/crater on or near its peak. Are they all old water volcanos?

What fun! Thanks.

Is there any more speculation from the mission team on these varied terrains? My untutored observations:

1. Plains with curved fractures/grooves, but also several long (and short, at higher rez) linear fractures/grooves
2. Looks for all the world as if "1-like" terrain melted and flowed South
7. Appears as if 1-like terrain partly melted and smeared South, carrying dark material in the curved fractures with it (perhaps also between red 2 and red 3)
3. Red 3 looks like a circular feature, with possible concentric rings?
6. If this is representative of other dark equatorial terrain, it looks like highlands (my impression was that the dark features on Pluto's Charon-facing side were lowlands

Habukaz: I had some confusion at first, interpreting your anatomical observations. As you face a heart, the "left ventricle" is actually on the right, and visa versa. I'm not trying to be cute. If I was, i would go further to suggest that your "northernmost parts of the left ventricle" are actually the right atrium (north of the right ventricle). :-)

Perhaps not dunes, but a continuation of the striations (associated with venting ala Enceladus?) partially buried in whatever deposition material makes up the flat terrain.

Going back to the Charon side which we will never see again (except in Charon light) I find the terrain extraordinary. Not to get too technical here, but the "wrinkles" look like MC Escher lizards. What are they? More interesting, the feature at 4 o'clock looks very different in this image, compared to others where it looks more crater-like. In the blow up on the far right, I have highlighted something that reminds me of the way Europa's cracks and surface displacements often overlay one another. Is the lighter material (highlighted as yellow) volcanic flows across the dark line (highlighted as red) that extends out from the circular feature? Others have already noted the doughnut-like look of several of Pluto's presumed craters.
