People tend to check in during these times:
Blackcomb Glacier is great near-country experience. Access via Glacier Express Chair, Showcase T-Bar and then a short boot pack.
Suck it up on the T-bar and hike up the hill. Totally worth it.
An epic and famous run on the mountain. Hit it early though before the road out turns to a slow, sloppy mess. For those with the proper avalanche equipment - access EPIC spring lines from here!
Score perfect turns on a powder day on the Blackcomb Glacier. Access via Glacier Express Chair, Showcase T-Bar and a short boot pack.
ski Horstman Glacier - you will like it (I did it with my Telemark gear) right after Olimpics took place in this area
