I'm sorry, Caleb, but Revelstoke will not be getting a park anytime soon. Quite honestly, the culture at Revy--or Rossland*, or Kicking Horse, or Nelson for that matter--kind of precludes it. (Although that doesn't rule it out entirely.) There are multiple reasons for this.
1. Revelstoke isn't a place where families go on vacation. At least, not in the same sense as, say, Vail, or Lake Tahoe, Whistler, or Park City. The clientele is decidedly different. There aren't really new skiers coming to Revelstoke to learn to ski. These are primarily seasoned, expert skiers who are interested in skiing powder, trees, cliffs, and big mountain lines. You need to understand that even now, Revelstoke and that entire area of B.C. is still more of a destination for cat skiing and heli skiing than it is for lift-serviced skiing. This further contributes to the culture in the area.
2. Locals tend to simply forego skiing entirely, switch to snowmobiling, try to find backcountry and sidecountry shots, and engage in other activities when "the snow isn't good."
3. There are very few--and I do mean very few--times when "the snow isn't good" somewhere in Revelstoke or near Revelstoke. Typically there are at least some aspects that are good, if not excellent, within a few miles in each direction. And even in the rare event that there aren't--who fucking cares? You're in Revelstoke--one of the extreme skiing capitals of the world! You can ski park anywhere, but this place is a unique experience that deserves to be treated as such. In all due respect to the freeskiing side of me who resists this idea, this is an area that simply must be skied in a certain way in order to get the full experience. It simply must.
Look, I understand the idea that a park in Revelstoke may seem like a good idea now, but I'd much rather the resort save that money and invest in further expanding the ski area boundary and constructing new lifts.
Schweitzer, by the way, is a completely different story. It's been my home mountain for nearly fifteen years. Not only does it only take an hour and a half to get from Spokane International to Sandpoint, and not three hours as you falsely claimed, but I'd say that the percentage of out-of-area visitors is only somewhere between 30-40%. (For a resort the size of Schweitzer, that's not great.) As well, Revy gets as many as 300 more inches of annual snowfall than Schweitzer, and as great as Selkirk Powder Company is, it's more of a novelty than a culture-builder. The comparison between the two is so faulty that it's laughable.
Look, a park in Revelstoke will come eventually as the resort continues to grow. Just not yet.
