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
Buttermilk, in United States, runs from 2,402 m at the base to 3,012 m at the top. Its mapped area is about 4.0 km across, with 50 marked runs and 8 lifts (about 41 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 185 cm of snowfall a season, 1,281st (tied) of 3,069 worldwide and 107th in the United States. Its winters are fairly steady; even the leanest, 2017/18 (138 cm), reached 75% of the average. December brings as much snow as January here (49 and 39 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.
96% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

This ski area does not put a camera on its own slopes. What follows are nearby cameras, not the pistes themselves.

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 |
|---|---|---|---|
| Aspen Highlands | 4.4 km | 194 cm | 1201 |
| Aspen Mountain | 5.3 km | 194 cm | 1201 |
| Aspen Snowmass | 7.1 km | 172 cm | 1401 |
| Crested Butte Mountain Resort | 34.0 km | 240 cm | 800 |
| Spring Gulch Trail System | 41.0 km | 158 cm | 1564 |
The most snow falls in March. March brings as much as January, or more. In amount, March brings 50 cm, more than the median of 30 cm.
Across the 12 winters measured, the average is 185 cm, and 7 of them fell short of it. The leanest was 2017/18 with 138 cm; the biggest was 2022/23 with 251 cm (1.8 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.
