I know i guy who went there and this is a short list I have comprised from his tellings
1. BE AVALANCH LEARNED: Allegedly it's one of the most prone and dangerous places, and due to the lack of modern rescue procedures it makes it even more crazy.
2. Be a super fit pow skier: Pow gets so deep and light it's dangerous to stop, and there are 0 groomed runs to rest and chill out on
3. Don't use nice skis, apparently it's core shot galore out there
But if you go you will have some killer stories and a great, unique experience!
