Whose snowstorm is it, anyway?
This is a topic that was posted on another Tolkien board (Finduilas' ezboard), and I'd like to see what people say about it here.
What do you think caused the snowstorm and avalanche when the Company attempted the Redhorn pass?
It's pretty clear that it wasn't a natural occurrance. Some of the possibilites include, Saruman (not too likely I think), Sauron, and the mountain itself.
