(8) Snow Line
The main thing that makes this such a hard poem to figure out is the fact that it isn't finished. It's really difficult to even take guesses when so much of the material is missing. Add that to the overall length, the archaic language, and a healthy dose of both Christian and pagan symbolism, and you've got a serious climb ahead of you for this one. Of course, once you get up there, you'll find that there's even more to see from that height.
