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.Snow report on the official site ↗
Trollhaugen Ski Area, in United States, runs from 290 m at the base to 362 m at the top. Its mapped area is about 1.3 km across, with 29 marked runs and 9 lifts (about 7.2 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 66 cm of snowfall a season, 2,697th (tied) of 3,069 worldwide and 483rd in the United States. It swings a lot from year to year: the biggest winter, 2022/23 (117 cm), brought more than 3 times as much as the leanest, 2014/15 (38 cm). December brings as much snow as January here (21 and 14 cm on average).

97% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.
The most snow falls in December. March brings as much as January, or more. In amount, March brings 16 cm, less than the median of 30 cm.

Niseko is 526th in the world for snowfall. Zermatt is 554th, Jackson Hole 924th, Aspen 1,201st. Measured identically across 3,069 ski areas, the names everyone books and the places it actually snows turn out to be two different lists.
