We do not show a snow depth here. The weather model we use reports snow lying on the ground — it knows nothing about grooming or snowmaking, and it is not the base depth a ski area publishes. In Japan we can check our figures against 234 weather stations. Outside Japan there is nothing to check them against, so we do not print a number we have not verified.

The five add up to the 100-point Powder Score: more fresh snow, more on the way and colder air all push it up. How we measure
Eagle Rock Ski Resort, in United States, runs from 399 m at the base to 549 m at the top. Its mapped area is about 1.3 km across, with 9 marked runs and 4 lifts (about 2.6 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 74 cm of snowfall a season, 2,633rd (tied) of 3,069 worldwide and 450th in the United States. It swings a lot from year to year: the biggest winter, 2016/17 (108 cm), brought more than 3 times as much as the leanest, 2015/16 (32 cm). January is usually the snowiest month, with about 22 cm.
Counted from the runs and lifts drawn on OpenStreetMap, within the boundary of the ski area. These are not the resort’s own published figures.
82% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

Modelled from weather data the same way at all 3,069 ski areas we cover. These are not the resort’s own published figures.
Within 50 km in a straight line. Ski areas in the same weather-model cell (about 30 km across) get the same figure.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Jack Frost Mountain Resort | 43.0 km | 90 cm | 2478 |
| Big Boulder Ski Resort Area | 45.0 km | 85 cm | 2528 |
The most snow falls in January. March brings 73% of January’s snowfall. That is a steeper fall than the median for ski areas in the United States (85%): the snow here is concentrated early in the season. In amount, March brings 16 cm, less than the median of 30 cm.
Across the 12 winters measured, the average is 74 cm, and 5 of them fell short of it. The leanest was 2015/16 with 32 cm; the biggest was 2016/17 with 108 cm (3.4 times as much).
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
