No snow yet. Snow depth and the seven-day outlook appear once snow is on the ground or forecast.
A weather-model figure, worked out the same way for every ski area, and lower than what actually falls. Use it to compare ski areas, not against the resort’s own totals. How we measure →
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.

Sun Valley - Dollar Mountain, in United States, runs from 1,813 m at the base to 2,002 m at the top. Its mapped area is about 2.3 km across, with 28 marked runs and 5 lifts (about 13 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 166 cm of snowfall a season, 1,457th (tied) of 3,069 worldwide and 151st in the United States. It swings a lot from year to year: the biggest winter, 2016/17 (287 cm), brought more than twice as much as the leanest, 2020/21 (100 cm). December brings as much snow as January here (48 and 36 cm on average).
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 |
|---|---|---|---|
| Sun Valley - Bald Mountain | 4.5 km | 194 cm | 1201 |
| Rotarun Ski Area | 21.0 km | 134 cm | 1892 |
| Soldier Mountain Ski Area | 46.0 km | 211 cm | 1048 |
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.
94% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

The most snow falls in December. March brings as much as January, or more. In amount, March brings 38 cm, more than the median of 30 cm.
Across the 12 winters measured, the average is 166 cm, and 6 of them fell short of it. The leanest was 2020/21 with 100 cm; the biggest was 2016/17 with 287 cm (2.9 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.
