in a so far tough season.
Very tough. The 11 major Northeast areas I track average 48% open now. That's the second worst since I started tracking in 2003-04. Interestingly, the only lower season was 2006-07, which turned around in a big way with an excellent February-April.
I've used those stats too, though differently, and in conjunction with estimated total skier visits.
Acreage / estimated skier visits is my measure for minimizing skier density
Vertical transport feet / estimated skier visits is my measure for minimizing lift lines.
Skier visit data is fuzzy and I put in a fair amount of effort to get that back in 2015. More and more areas are refusing to publish that info, so the quality of that data is degrading.
My skier density measure reflects an overall ski season, while Harvey's is better for the worst case scenario, like a weekend powder day.
It was very easy to go into that 2015 spreadsheet and try out Harvey's formula on the 89 areas I was analyzing then. No surprise it didn't match up too well.
1) My numbers are 7 years old, and I while was crunching those VTF numbers I made the error of not saving the details.
2) I adjust some of the acreage numbers where I believe that stat significantly over or underestimates usable ski terrain.
Most eastern areas worthy of my attention (18 out of the 89) have some tree skiing and get an upward acreage adjustment. Stowe is an extreme example. Its skier density number by my spreadsheet is 46.5 (Harvey has 41) using published 485 acres but is only 14.9 using a more realistic 1,500 acres. The latter number was informed by an online debate with JSpin, who argued for 2,500 acres.
So in another attempt to lure Harvey west, here's the Top Ten List by HIS skier density measure:
1) Powder Mt. 2.9
2) Castle Mt. 3.1
3) Kicking Horse 3.2
4) Mad River 4.2 (I use 700 acres)
5) Sunlight 4.7
6) Panorama 4.9
7) Grand Targhee 5.0
8) Alta 5.0
9) Wolf Creek 5.1
10) Whitewater 5.2
Jay at 10.0 (assuming 1,200 acres) is the next best eastern area at #43. Eastern areas comprise 12 of the highest 13 skier densities by Harvey's stat with acreage adjustments.
