for the most comprehensive info. There is also a book available. Maybe search on Amazon to find what the title is.
Eisman near Vail is supposed to be good for BC skiing, but I've never been there.
I've been to Fowler-Hilliard in the summer, and Resolution Mountain looks like it would be good. I belive there is snowcat skiing that may access that area too. I've also been to Polar Star, also in the summer. I climbed New York Mountain, and there might be some good routes up there.
As always, be careful and use avy gear at any of these spots. The ones I mentioned are at treeline, and the skiing is wide open above treeline bowls and such.
