Targhee season snowfall is 76 inches, which is exactly its November average. Other factors to opening lots of terrain fast.Wow. How much snow has fallen there so far? They must do a lot of summer/fall grooming.
1) Topography: intermediate vs. steep, grassy vs. rocky. Jackson, Snowbird, Palisades take some time to get much open even when they get abundant early snow.
2) Number of lifts needed. Targhee only has 6 to open 100%. Vail has had as much snow, similar topography and has 9 lifts open out of their 34 total. In fairness Targhee has 2,602 acres while 35% of Vail's 5,289 is 1,851, not a huge disparity.
3) Historical track record. Targhee averages 72% open Dec. 1, which has to be the highest anywhere aside from Wolf Creek. So it's not unexpected and they are prepared.
4) As with the late season, and very important, is management attitude. As with closing dates, many areas won't adjust their opening dates or rollout of chairs/terrain before the Christmas holidays no matter how much snow they have. If you have a ton of lifts like Vail and Whistler, staffing is part of that equation. Those are areas to watch over the next month because both have lots of snow now and a good historical early season record. I'm guessing both are waiting for full seasonal staff to arrive.
For both early and late season, flexible operations are more likely with a drive-up population base, Mammoth being Exhibit A. Early and late season is part of the brand for Mammoth and Killington and early season is certainly that for Wolf Creek.
