Okay, I'll give this a nudge.
I wonder if many (any?) people other than the residents of Silverton and some core as-a-matter-of-principal environmental activists/groups are upset about this? Personally, I'm not particularly in favor of h/c skiing, but the basin around the ski area isn't in a designated wilderness area and has had the shit mined out of it.
I guess I'm just not familiar with any specific arguments against it, but I'd like to hear some. I'm going to have to cut a corner off my environmental activist card.
