It looks too see-through to be frozen over IMO. I don't know, maybe some parts will be frozen but definitely not all of that. You can really see through almost all of it except the very thick parts at the top.

I mentioned this before, maybe the ice is simply a barrier over the land created by Kyurem, creating it's territorial boundary around the region. Also glaciers in cartoons and game are sometimes way more transparent than it is in reality.
