Tips for a long run in Sundered Pass?

Second time to SP and I've decided to challenge myself with seeing how long I can stay there. Aiming for a month this time. I'm not overly worried about the wolves, I've gotten pretty good at dealing with them and I'm going to be keeping a very slow and careful pace where I think I can thin them out and keep the whole wolf situation under control. I'm hoping to L5 my bow skill here (sure will have plenty of targets for it!)

The cold's going to be a problem. Probably most of the time I'll be at the bottom where it's warmer and food and fuel isn't too much of a concern. I'm assuming I may have to travois up a whole lot of firewood to the top if I stay there for any length of time. In general trying to stay alive at the top's not going to be easy. I haven't done the Tales yet, I should have started it when I was in Transfer Pass but I didn't want to go to FA and didn't think about it until I was already in SP.

Any other suggestions for surviving for a long time here? It's a cool map, I want to get to know it better, but it's possibly the most challenging one.
