I'm interested in getting up there as well.
It looks to me like the Bear Lake Trailhead is a good starting point-- Flattop mountain banana bowls, Ho Hum, terrain park, Dragon tail- stuff in Tyndall Gorge.
I also want to check out Hidden Valley (an old ski resort that probably has some moderate terrain.
PM me if you want to get out. I just moved to Boulder, but have my Avy 1 and some BC experience.
