Seems to be a lot of dispute on this subject... I think it's ice from the interior, but what does everyone else think?
Edit: This world seems very complex so the question could perhaps be phrased as 'which of these options is most responsible for the Iapetan dichotomy?' |

Ugordan,
I think that I see wide openings (holes) on the ice in this particular image, that seem to have thick white walls and are partially black at the bottom. This gives me the impression of melted ice on top of black terrain. If it was just white holes filled with black material melting the ice, one has to explain the black basin walls, which I find hard to do |
