I skied Silverton last year after 3 fresh feet fell that night. It's not like a resort either, 93ft on top of hard). it's 3 feet on top of more bottomless light deep powder. I can honestly say it was the best day of skiing of my life and i have skied 14 years 60-80 days a year. The terrain IS orgasmiclly sick. 50 degree chutes and faces in powder so deep you have to lift you elbows a bit so they are out of the snow and you can pole plant. As for the avy stuff, I got my beacon and did some research and reading. I practiced with my beacon and became familiar with it. the guides know their shit and they will keep you safe, but don't go with the resort mentality. As for the value, 100 $ is alot but if you compare it to heli skiing, it's cheap. We went with a bunch of guys who heli and cat ski in BC and Alaska all the time and they said after skiing silverton that it was just as good of snow, terrain for about 1/4 of the price. If you go, bring a beacon, shovel, probe. You don't need Avy 1 certification but if your gonna take the course go for it. Also, bring the fattest pair of skis you own. At least 85 mm waists. And also bring an extra pair of underwear cuz you'll probly shit yer pants when you see the runs!
If you have any questions about it MSG me.
