Ah! Finally seeing craters, and most of them look small and deep to me. The craters I was expecting where the shallow slumped craters that we see on Ganymede and now Ceres, where an object hits a slushy surface and instead of melting rock, it melts a mix of rock and ices. The "heart" is ice, and I think we all figured that out in the other thread. The dark area, Cthulhu Regio (my new favorite name in the solar system!) looks older and has more evidence of cratering.

Look at the better full globe images and you can see round areas that look like anything but weathered impact craters. From the scales used, they all look under 100 miles wide. In Slide 2b, you can see what looks like a larger complex crater with concentric rings, much like we see on the earth and moon and the smaller moons of Saturn. There are at least two craters with central peaks that look sharper to me, but that may be a trick of the camera angles, so hard to tell at this point.

Now we wait for the high res images!
