I learned to snowboard on that hill, it was one of the first places around here to allow (and, equally importantly, to rent) snowboards. I mostly ride at Stevens Pass now, which is a bit further north and higher up...
The roads to both locations have been closed quite a bit lately due to avalanche concerns, and are still closed at the moment, so regardless of how the area operators feel about avalanche danger, the Department of Transportation isn't letting anyone up there. Snoqualmie hopes to re-open tomorrow (that slide happened at one of their four base areas, the other three are probably still OK) but Stevens plans to be closed until Friday.
And it's raining in both areas as I write this. :(
