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.

Sleeping Giant Winter Sports Area, in United States, runs from 2,022 m at the base to 2,263 m at the top. Its mapped area is about 1.2 km across, with 18 marked runs and 3 lifts (about 5.6 km of piste in all).

Over the last twelve winters the ERA5 weather model gives it 159 cm of snowfall a season, 1,553rd (tied) of 3,069 worldwide and 170th in the United States. It swings a lot from year to year: the biggest winter, 2016/17 (254 cm), brought more than twice as much as the leanest, 2023/24 (120 cm). December brings as much snow as January here (45 and 32 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.
