    Heck, even if they used Ratnik BSGX-2's, they'd still make snow in plenty of time:

    31F WB ... 14:1

    1 gun every 100 feet (standard) ... 250 cfm & 17.8 gpm ... 8500 cfm, 605 gpm

    I'm highly confident Killington has more than an 8500 cfm air supply.

    3400 x 250 = 19.5 acres

    1.5 ft depth = 29.3 acre-ft of snow

    1 acre-ft = 180,000 gallons (fairly wet man-made snow)

    6.0 days non-stop at 31WB.

    Now considering it will be colder than that, they'll put out more snow. And they can also make a lot more up top and push it down if need be.

    Considering that the hydrants are closer than 100 ft on Supestar, they'll just make snow that faster.



    They have more than enough ability to open Glades > base & Superstar by Thanksgiving except in the very warmest of winters, where no ski area will be making any snow at all.

    If you don't like this math, use logic: replace filling out Snowdon with opening Superstar.

    Following the '80 Olympics they let the sides of the upper trails grow back.

    Superstar is 3400ft long, and roughly 200ft wide, 300ft wide at the bottom. Lets call it 15 acres. They need to put down roughly 5 feet of snow to get the base depths required to groom the hill nice and flat.....trust me, race teams will not be happy if they keep shanking rocks. So that's 75 acre feet of snow. About what it would take to get the northridge triple open and a snowdon route open, with decent but marginal coverage, to the bottom of the K-1. They have to make all this snow by around Nov 20th, the weekend prior, so they can get the hill prepped and allow some training on it.

    Now, without getting into the details of the low-e snowguns, which are FAR less effective than old style snowguns at marginal temps..........what has Killington's past performance been like? Well, some years they do great, and have the snowdon route plus many other trails open by thanksgiving, say 150 acre feet of snow (after melting) by Nov. 20th - this is the max. The average is probably somewhere around 100 acre-ft after melting by Nov 20th, enough to get open top to bottom on the K-1, plus a few more trails. In a poor year, they have just a few trails open off the northridge triple, or are closed entirely, with only 10-20 acre feet of snow on the ground.

    Now what about this race? They are contractually commited to host it and if they can't pull it off, they stand to loose a pile of money. Hopefully they have insurance for this sort of thing. Lets compare senarios based on past winters - each of these happen about a third of the time:

    Cold November: No problem, race happens, skiing for public likely on other trails off superstar chairs, plus K-1, NRT and Snowdon.

    Average November: Race draws most snowmaking resouces for first half of November. Superstar might be open to public for first half of November. Snowmaking on K-1 / NRT starts once Superstar looks to be in good shape, public skiing only on NRT for Thanksgiving weekend (45 minute lift lines).

    Warm, rainy November: Snowmaking focused entirely on Superstar, during small overnight windows of snowmaking, with several rain events melting snow. No public skiing on Thanksgiving weekend.

    So, by my estimates they have a 2/3rd's chance of having either NO public skiing, or skiing on the NRT only for Thanksgiving - both of those are pretty bad senarios.

    This is not even taking into account the chances of an ice storm, major rain storm, or 70F thaw the week of the event.

    EPIC FAIL!
    5 feet of snow? You're nuts - take it from someone who has to budget and create snowmaking plans, 2 feet is adequate and there will be no rocks. Cut your #s way down.

    Also, you are patently wrong that Low-E guns are ineffective, you just need more. Every big player but K uses them early season, but they have density.

    And what really is your point?

    That was mid-season snowmaking at low temperatures. Apples and oranges. The efficiency bump from using low-E guns decreases with lower temperatures.

    And we have to think about other things... What's the reasoning for using those guns? Was it windy that day? Did they not have enough SnowLogics? Were they making sure they're still proficient with that gun? Are those even K3000s? That's pretty blurry and hard to tell. Their Ratniks are on old K3000 tripods. Is it because K3000s and Ratniks have better throw (100ft vs. 50ft. for SnowLogic ground guns) as it makes the piles made during the day spread out more and better to ski on? Or did they just want to save groomer money?

    And we don't even have to argue about the SnowLogics making enough snow anymore because:

    They're admitting they'll have rental compressors for making snow over on Superstar.

    I don't think it's necessarily because they fucked up with the Dew Tour. I imagine it's the USSA's requirement to have the even there. USSA pays a lot to Copper to have early season training.

    You're on crack if you think they will hold an FIS event on a foot and a half of snow. Killington won't even open a trail with that kind of base depth. And that's not even accounting for snow melting.

    Haha what?!? Killington routinely opens early season trails on far less than 18 inches.

    Newpylong says he does this stuff for a living. I will take his word over yours.

    You've obviously never hiked Killington in the summer. Most of their snowmaking trails are very rugged, and intended to have many feet of snow blown on them. Upper and Lower Superstar need about 5 feet of snow to be opened and groomed.

    Maybe, just maybe they do a little grading and trailwork in the problem areas to avoid having to make so much snow.

    You would not be able to get your mower up and down a trail needing 5 feet of snow to be open. Superstar isn't mowed by hand.

    This is rugged?





    The only thing they need to worry about is getting over the water bars.

    This is the kind of trail you need 5-feet on:
