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
Espace Haute Maurienne Vanoise, in France, runs from 1,306 m at the base to 2,948 m at the top. Its mapped area is about 44 km across, with 371 marked runs and 79 lifts (about 211 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 299 cm of snowfall a season, 484th (tied) of 3,069 worldwide and 74th in France. It swings a lot from year to year: the biggest winter, 2017/18 (577 cm), brought more than twice as much as the leanest, 2021/22 (210 cm). March still brings 76 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 49% of the vertical on the runs descends to the north or east. The most common direction is north (38%).

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.

The most snow falls in January. March brings 87% of January’s snowfall. That is a gentler fall than the median for ski areas in France (77%). In amount, March brings 76 cm, more than the median of 55 cm.
Across the 12 winters measured, the average is 299 cm, and 8 of them fell short of it. The leanest was 2021/22 with 210 cm; the biggest was 2017/18 with 577 cm (2.7 times as much). For 26% of the 244 ski areas in France the leanest winter was 2016/17; 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.

A Black Run in Colorado and a Black Run in Austria Are Not the Same Thing. The Maps Prove It.Across 2,888 ski areas: 39% of American runs are graded advanced or harder, and 9% of Austrian ones. Nobody thinks Austria is four times gentler. The grades are measuring different things.
