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

Lost Trail, in United States, runs from 1,960 m at the base to 2,495 m at the top. Its mapped area is about 4.5 km across, with 56 marked runs and 8 lifts (about 36 km of piste in all).

Over the last twelve winters the ERA5 weather model gives it 188 cm of snowfall a season, 1,259th (tied) of 3,069 worldwide and 102nd in the United States. It swings a lot from year to year: the biggest winter, 2025/26 (256 cm), brought more than twice as much as the leanest, 2014/15 (110 cm). December brings as much snow as January here (53 and 35 cm on average).

89% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.
