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
Arctic Valley Ski Area, in United States, runs from 772 m at the base to 1,192 m at the top. Its mapped area is about 2.1 km across, with 21 marked runs and 3 lifts (about 9.6 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 231 cm of snowfall a season, 865th (tied) of 3,069 worldwide and 63rd in the United States. It swings a lot from year to year: the biggest winter, 2015/16 (392 cm), brought more than twice as much as the leanest, 2025/26 (146 cm). December brings as much snow as January here (70 and 70 cm on average).
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.
Only 26% of the vertical on the runs descends to the north or east. The most common direction is west (69%).

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 |
|---|---|---|---|
| Hillberg Ski Area | 16.0 km | 133 cm | 1909 |
| Hilltop Ski Area | 17.0 km | 171 cm | 1407 |
| Alyeska Resort | 39.0 km | 574 cm | 50 |
The most snow falls in December. March brings 59% 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. For skiing, though, the amount matters more than the share: March brings 41 cm, more than the median of 30 cm.
Across the 12 winters measured, the average is 231 cm, and 7 of them fell short of it. The leanest was 2025/26 with 146 cm; the biggest was 2015/16 with 392 cm (2.7 times as much). For 33% of the 534 ski areas in the United States the leanest winter was 2015/16; here it was a different one.
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
