Thanks :-) I wanted to show My model of Ahuna Mons, with my hands (12x17 cm - 1cm about 1260 km) NO 3Dprinter (in the link there is also my occator crater): I do not know if I can to insert here or remove moderator http://antidotumtarantulae.altervista.org/...ula_planet.html

Cerealia Facula in Occator Crater:

Amazing! I do not see a single crater in the top mosaic. A surface as young and fresh as Sputnik Planum on Pluto?

Amazing!
I really didn't expect we will see this thru Dawn's eyes. Trully extraordinary engineering and mission planning accomplishment. Reversed perspective of that mosaic makes more sense for my brain:  Occator context image |

My quck ICE version:
I tried using colour from an earlier colour image, but there is strong purple fringing there. Of course, would be nice to see the central dome in such resolution. -------------------- Curiosity rover panoramas: http://www.facebook.com/CuriosityRoverPanoramas

"The geometry of this feature is similar to a mesa or large butte with a flat top." http://photojournal.jpl.nasa.gov/catalog/PIA22477 A sodium carbonate-topped hill. Interesting that some of it streaked downslope. P.S. Actually, looking at it in the surrounding context, it's more like a cliff or escarpment, because the south-western side of it seems to be level with the dark part of terrain, whereas north-east side drops off sharply towards the main mound.
Most of the flat white area here is slightly darkened, probably by space weathering and dust, but the bright edges with downslope streaks reveal fresher material. I wonder what it means in terms of dynamic processes on Ceres.

It seems like exposure of sulfur after volcanic eruption, but this should be salt or sodium carbonate [wildespace].
