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
Mad River Mountain, in United States, runs from 356 m at the base to 443 m at the top. Its mapped area is about 1.4 km across, with 10 marked runs and 11 lifts (about 4.3 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 48 cm of snowfall a season, 2,831st (tied) of 3,069 worldwide and 522nd in the United States. It swings a lot from year to year: the biggest winter, 2020/21 (76 cm), brought more than twice as much as the leanest, 2015/16 (26 cm). January is usually the snowiest month, with about 19 cm.
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.
64% of the vertical on the runs descends to the north or east; plenty of the terrain faces the sun as well, so the lean is modest.

Modelled from weather data the same way at all 3,069 ski areas we cover. These are not the resort’s own published figures.
The most snow falls in January. March brings 32% 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. In amount, March brings 6 cm, less than the median of 30 cm.
Across the 12 winters measured, the average is 48 cm, and 6 of them fell short of it. The leanest was 2015/16 with 26 cm; the biggest was 2020/21 with 76 cm (2.9 times as much).
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
