Dry Hill Climate Change Profile

Overall 2

Winter Resilience Score

More climate-resilient than 3% of Eastern & Midwestern resorts · 2% of all North American resorts

#65 of 68 in the East & Midwest · #215 of 220 overall

What goes into it, compared with Eastern & Midwestern resorts:

  • Season length at +2°C 20% better than 12%
  • Rain on the snowpack at +2°C 40% better than 7%
  • Snowmaking weather at +2°C 10% better than 19%
  • Terrain orientation 30% better than 15%

* A ranking against the North American resorts we rate, not a grade out of 100: 100 = most resilient in the field, 50 = middle of the pack. Higher scores mean the resort's terrain and weather profile are more resilient in preserving winter conditions, both today and in a future of warmer temperatures.

Dry Hill Climate Change Takeaways

  • Rain potential: About 49% of winter precipitation falls as rain today, rising to about 66% with 2°C of warming. Ranks #66 of 68 Eastern & Midwestern resorts for rain resilience (#204 of 220 overall).
  • Season length: About 70 naturally skiable days a season today (Nov–Apr); about 14 with 2°C of warming (56 fewer).
  • Snow preservation: Terrain faces mostly north and gets about 32% less winter sun than neutral terrain. Its orientation holds snow better than 91% of Eastern & Midwestern resorts (94% of all North American resorts).
  • Base area viability: At risk: the 700' base has about 63 naturally skiable days a season today, about 10 at +2°C.

Dry Hill Rain Resiliency Score

7

Less rain risk than 3% of Eastern & Midwestern resorts · 7% of all North American resorts

#66 of 68 in the East & Midwest · #204 of 220 overall

About 49.4% of winter precipitation falls as rain today, about 66% at +2°C.

How well Dry Hill's winter precipitation holds up as snow rather than rain. We rebuilt 40 winters of hourly weather at the resort's base, mid-mountain and peak, then estimated whether each hour's precipitation fell as rain or snow from temperature and humidity. To see what warming would do, we re-ran the same winters 1°C and 2°C warmer. The score is a ranking, not a grade: 100 = least rain risk in the field, 50 = middle of the pack.

The first two columns are the real observed weather record, split into two equal halves. * The +1°C and +2°C columns are stress tests: the full observed record replayed with that much warming added, so they show sensitivity to warming, not a forecast for a specific year.

Dry Hill Season Length

70 days

More naturally skiable days than 24% of Eastern & Midwestern resorts · 11% of all North American resorts

#52 of 68 in the East & Midwest · #196 of 220 overall

70 of 181 possible days today (Nov–Apr), about 14 at +2°C.

How many days a season Dry Hill has enough natural snow to ski, November through April. We simulated the snowpack day by day for 40 winters at the base, mid-mountain and peak — snow piling up, melting on warm days, and getting eaten away by rain — then ran the same winters 1°C and 2°C warmer.

700' Base 63 30 10
Skiable by Christmas 13% → 0% of winters with a skiable base on Dec 20, today → +2°C
Rain-on-snow days 7.4 → 1.6 per season with real rain (5+ mm) falling on the snowpack — slush, then ice
Snowmaking hours 510 → 370 hours cold enough to make snow at the base, Nov–Dec
Why rain matters more than you'd think

Warmer winters don't just turn some snowfall into rain. Rain also eats away the snow that's already on the ground, in four ways:

  1. The rain itself is warm. This is the smallest effect — a soaking rain only melts a sliver of snow directly.
  2. Rainstorms bring warm, humid air. When moist air hits the snow, water condenses on the surface and releases heat. That's the main reason a single warm storm can wipe out a foot of base in a day.
  3. Rain primes the snowpack to melt. Cold snow soaks up rain and refreezes it, which warms the whole pack. Once it's soaked and at the melting point, every warm hour after that goes straight to melting.
  4. Rain wrecks the surface. Even when the base survives, rain leaves slush that freezes into ice. That's why we count rain-on-snow days separately — they hurt your ski day even when the snowpack doesn't disappear.

Our model simulates all four, using a simplified version of the snowmelt model the U.S. National Weather Service uses for river forecasting.

Natural snow only — no snowmaking or grooming, so resorts that make a lot of snow stay open longer than these numbers. “Skiable” means at least 3 inches of snow-water in the snowpack (roughly a 12–18 inch settled base). Snowfall is scaled to match Dry Hill's average snowfall. Melt follows the sun on Dry Hill's actual runs: shady, north-facing slopes hold snow longer than sunny ones. * Stress tests, not forecasts: the same winters replayed warmer. The model was checked against real snowpack measurements at 105 SNOTEL stations in the western U.S.; there are no SNOTEL stations near Dry Hill, so treat these numbers as a rougher estimate.

Dry Hill Snow Preservation Score

−32% less sun

Terrain holds snow better than 91% of Eastern & Midwestern resorts · 94% of all North American resorts

#7 of 66 in the East & Midwest · #13 of 216 overall

Dry Hill's runs get 32% less winter sun than the same slopes would facing every direction equally. Typical resort: 17% less.

How well Dry Hill's runs are oriented to hold onto snow. North-facing slopes get less direct sun and keep snow longer; south-facing slopes lose it faster. We measured the direction and steepness of 11 mapped runs and compared the sunshine they receive with what the same slopes would get if they faced every direction equally, so this score reflects terrain orientation only, not latitude or elevation (those are covered by the rain score above).
