Sleeping Giant Winter Sports Area
Sleeping Giant Winter Sports Area is a ski area in United States, at about 2,077 m. 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).
Snow depth and the seven-day outlook appear here once snow starts to fall. Until then, the long-run record comes first.
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.
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
Month by month
Month by month, the most snow falls in February. March brings as much as January, or more. In amount, March brings 35 cm, more than the median of 30 cm.
Winter by winter
Across the 12 winters measured, the average is 159 cm, and 7 of them fell short of it. The leanest was 2023/24 with 120 cm; the biggest was 2016/17 with 254 cm (2.1 times as much).
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
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
97% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.
