TSP went in there and spent five days doing sled and skinning accessed BC last year. The segment didn't make the movie, but it's in the bonus features of Act Natural.
Lots of very interesting BC. Most of it will be fairly obvious; we found good stuff all over the northern shoulder of mountain that the ski area is on. A series of roads connects those chutes back over the little pass North of the parking lot.
We really battled low/constantly melting/refreezing snow, so I'd be curious to see what that place is like in a big, big cycle.
Fbook says they're open this year. Hoping to make it over or a day or so to get the lift experience.
