My wife and I leave tomorrow for a week in the San Juans (staying in Telluride and Silverton) with plans to ski Telluride, Purgatory, and a pre-booked 3 days at Silverton.
Purgatory got 30 inches last week and Telluride 21. Telluride is 74% open, which tells you that the steepest terrain in Coloradod is not yet ready for prime time. I do not know where snowtrekker lives, but Silverton requires several days (and preferable a week) of sleeping at altitude before you will be routinely hiking above the lift that tops out at 12,200 feet.
but many western resorts also consider much of March as prime season
That is primarily a Colorado phenomenon IMHO, as evidenced by Vail's premium day ticket pricing for the entire month that does not apply to their resorts in other states. Mammoth gets a bump during California breaks that are more tied to Easter. But an April spring break week is not at the level of President's Week for example.
I would expect the Rockies region to be down some in this year’s NSAA Kottke Report.
What are the largest year-over-year declines in US skier visits? Two stand out.
1980-81 (72% of normal snow, 71% in Nov/Dec) was 18% lower than 1979-80 (94%/82%). Snowmaking was primitive then vs. today.
2011-12 (81% of normal snow, 66% in Nov/Dec) was 16% lower than 2010-11 (130%/142%). Some of that has to be ascribed to the record high snowfall in 2010-11, which tied 2007-08 for highest overall skier visits at that time. The 2011-12 decline was only 10% over a skier visit trendline for that season. So my best guess would be less than a 10% drop in US skier visits in 2025-26 to maybe 56 million, because the Northeast is having a good year. In 2011-12 the Pacific Northwest was the exception region with high snowfall.
Rockies region skier visits declined only 9% in 2011-12 vs. 2010-11 but 39% in 1980-81 vs. 1979-80.
2025-26 was similar to the above seasons at the end of December but as of mid-February had 68% of normal snow (58% excluding Northeast). So it's clearly the worst aside from 1976-77 at that point. As of the end of December 1976-77 had 51% of normal snow (38% excluding Northeast). January 1977 was not much better than January 2026.
