I have a bit of a different view than Ron on skiing hairy stuff. For me, if there is a great reward at the bottom of the chute, then I will push myself to do it, but solely so that I can ski the great powder lower down that less people will ski because the price of entry is so high. At Big Sky there is a colouir that is very tight and it runs for 1000 feet. Essentially you are doing hop turns or near hop turns for 1000 feet. But there is no great powder field below it. I have had a few shots to ski this and I have passed every time. Doing hop turns for a 1000 feet is not my idea of skiing!! But... to each his own.
On Big Sky, the conditions depend alot on when you go. I have never seen a mountain that eats skis like Big Sky. It basically eats them for breakfast, lunch and dinner!! Early season at Big Sky can be sketchy. Now in my thrid season in SW Montana, I can tell you that coverage can be lean in December and January. I gets better in February, and in late Feb and into March we start to see really big dumps of snow. March is the best time to sky Big Sky. As well, it can be just frigid in December and early January. I have gotten used to it, and I have the right gear and apparel to stay out all day when the high temp is 0-5 degress F. Usually by late Jan things warm up and in general from Feb1 to the end of the season temps are between 15 and 25F which is very skiable and quite comfortable.
One great thing about big sky is that even though they have as much skiable acreage as Vail (combined Big Sky with Moonlight Basin skiable with one lift ticket) it has the same amount of people as Fernie or Kicking Horse (very lean!). There are never crowds. Lift lines are a rarity, and it has terrain that will rival any ski resort in the world (all best skied when there is good coverage). The backside of Lone Peak is amazing, but it is really best skied on a bluebird day as it is way above the tree line and visiblilty can be incredibly challenging in low light.
Something to consider when coming to Big Sky. There are a few places on the mountain that you can only ski in pairs and they only allow skiers with becaons, probes, shovels etc. The North Summit Field is like this and it is some of the best skiing on the mountain. You need to go with someone that knows their way (I'm not quite there yet and I need many more trips down it to be able to fully know my way) because you can cliff out, but IMO this is a can't miss skiing experience. Without a beacon annd other Avy gear you won't be allowed to ski it. Ron, you should definitely plan on skiing this!! It's not that hairy, but several thousand feet of great off piste skiing. With fresh snow it is nirvana!!
Let me know when you guys are planning to go. Obviously if I can be out there at the same time I would love to ski with all of you.
