No snow yet. Snow depth and the seven-day outlook appear once snow is on the ground or forecast.
A weather-model figure, worked out the same way for every ski area, and lower than what actually falls. Use it to compare ski areas, not against the resort’s own totals. How we measure →
Elevation of the ski area’s centre point, taken from a digital elevation model. It is not the base-to-summit range.
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.

Col d'Ornon is a ski area in France, at about 1,432 m. Within 3.3 km of its centre the map shows 22 marked runs and 4 lifts (about 6.1 km of piste).
Over the last twelve winters the ERA5 weather model gives it 326 cm of snowfall a season, 378th (tied) of 3,069 worldwide and 64th in France. It swings a lot from year to year: the biggest winter, 2017/18 (606 cm), brought more than twice as much as the leanest, 2016/17 (230 cm). March still brings 79 cm on average, close to January, its snowiest month.
The nearest city of any size is Grenoble, about 28 km away in a straight line.
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.
