Gwynne Valley
Gwynne Valley is a ski area in Canada, at about 717 m. Its mapped area is about 0.6 km across, with 3 marked runs and 1 lift (about 0.9 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 55 cm of snowfall a season, 2,789th (tied) of 3,069 worldwide and 171st in Canada. It swings a lot from year to year: the biggest winter, 2021/22 (88 cm), brought more than 4 times as much as the leanest, 2020/21 (21 cm). December brings as much snow as January here (13 and 12 cm on average).

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 shape of the mountain
Which way the slopes face
90% 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 3,069 ski areas by one identical method. These are not the resort’s own published figures.
When it falls, and how winters differ
