I didn’t get to the ice park until after the single-block sculptures were judged, so I didn’t see them in progress. But I did get to see the multi-block sculptures at several stages. These photos are mostly of incomplete sculptures, so you get some idea of how they’re done.
The blocks may need to be piled up, and for this the artists have the help of heavy equipment. Scaffolding is available, and often needed to reach the surfaces to be carved. These blocks, for instance will be carved into the appearance of a stone bridge.
I’ll have photos of the winners up in a few days.
