Alright, so I was not sure where to exactly post this...so I hope this is the appropriate place. However, I need some help, and decided this would be a great place to ask.

What I'm currently working on is designing a temple set in the mountains. This temple would need to be self sufficient, which entails the ability to produce their own food. Farming in particular is giving me some trouble. The mountains in which I've placed this temple are rather rugged, and quite cold for the better part of the year.

Would anyone know anything about mountain farming? I've begun doing some basic research, however I'd like to see if anyone else has thought along the same lines as myself. It would be ideal if the denizens of this temple are able to farm for themselves, without relying on trade from villages or towns.

I realize this is quite the random question. However, any advice on where to look or any ideas would be most appreciated.
