A number of points here. I never know what is a wind hold and what is another issue like avalanche control. Powder Seeker , like other Alpine chairs, will not open until ALL avalanche control above the chair is completed. FYI, I'm told the same pitch that provides great expert skiing is the critical range for avalanches. Steeper and the snow will fall off on it's own, a little shallower and it is less challenging but also less likely to slide.
One or two additional blue runs will be added near the new Shedhorn Quad to allow more intermediates to share the experience of the backside of Lone Peak.
Powder Seeker proves the adage that "If we build it they will come". The line is usually short but there are 4-5 or 6 folks on most chairs when conditions are good in th eBowl and Upper Morningstar. The improved char has attracted a lot of skiers and everyone I know agrees there is enough terrain to absorb the traffic. I'm guessing they're expecting the same thing with the new chair on Andesite.
2020-2021 gondola design is not finalized but it will probably be a two stage with a mid mountain stopover. It may provide space for ski school students at a new mid mountain location. Food, restrooms and other facilities would be there to support ski school. The second stage of the gondola line will take guests to an as yet undetermined terminus near either the base of the Tram or the Powder Seeker. Another smaller restaurant would be located at this location. Moving the ski school and most of the magic carpets would relieve congestion in the base area and take a lot of traffic off Swift Current. Explains why new chair next year goes toward Andesite Mtn.
The complete repurposing of the top floor of the old Mall building will be the favorite upgrade for a lot of folks. It's a classy upgrade to the Base area and the first step of a complete remodeling of this building. Everything goes away except the bones of the original building.
