Pioneer Mountain Resort
Pioneer Mountain Resort is a ski area in United States. The terrain spans roughly 2545–2545 m above sea level. The mapped ski area covers about 10 km². Within 2.8 km of the centre, the map shows 100 marked runs and 14 lifts, totalling about 92 km of piste. Over the last three winters the ERA5 reanalysis gives it 145 cm of snowfall a season, 1639th (tied) of the 3,112 ski areas we measure worldwide. The model runs well below what resorts report, so the ranking is the meaningful part rather than the centimetre figure. 4 other ski areas lie within 120 km. Snow figures and the Powder Score are recalculated every day.
Elevation range is estimated by sampling points across the ski area.
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.

Runs and lifts
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.
The figures are for the whole of “Yellowstone Club”, which the map draws as one ski area.

The shape of the mountain
Which way the slopes face
73% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

How much snow it gets
Measured by us across 3,112 ski areas by one identical method. These are not the resort’s own published figures.
Compared with what is nearby
Within 50 km straight line. Measured the same way, so the ranks compare directly. Ski areas a few kilometres apart share a weather grid cell and can return the same figure.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Big Sky Resort | 5.7 km | 175 cm | 1306 |
When it falls, and how winters differ
Month by month
