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
Big Rock Mountain, in United States, runs from 201 m at the base to 487 m at the top. Its mapped area is about 1.7 km across, with 33 marked runs and 4 lifts (about 11 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 164 cm of snowfall a season, 1,485th (tied) of 3,069 worldwide and 155th in the United States. Its winters are fairly steady; even the leanest, 2025/26 (101 cm), reached 62% of the average. March still brings 41 cm on average, close to January, its snowiest month.
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 5% of the vertical on the runs descends to the north or east. The most common direction is west (81%).

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 |
|---|---|---|---|
| Aroostook State Park | 17.0 km | 168 cm | 1438 |
| Quoggy Jo Ski Center | 24.0 km | 160 cm | 1541 |
| Nordic Heritage Outdoor Center | 25.0 km | 160 cm | 1541 |
The most snow falls in January. March brings 93% of January’s snowfall. That is a gentler fall than the median for ski areas in the United States (85%). In amount, March brings 41 cm, more than the median of 30 cm.
Across the 12 winters measured, the average is 164 cm, and 5 of them fell short of it. The leanest was 2025/26 with 101 cm; the biggest was 2017/18 with 194 cm (1.9 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.
