Happy Jack Winter Trails
Happy Jack Winter Trails is a ski area in United States, at about 2,624 m. Its mapped area is about 4.1 km across.
Over the last twelve winters the ERA5 weather model gives it 84 cm of snowfall a season, 2,539th (tied) of 3,069 worldwide and 420th in the United States. Its winters are fairly steady; even the leanest, 2014/15 (54 cm), reached 64% of the average. December brings as much snow as January here (18 and 18 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.

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 March. March brings as much as January, or more. In amount, March brings 30 cm, about the same as the median of 30 cm.
Winter by winter
Across the 12 winters measured, the average is 84 cm, and 5 of them fell short of it. The leanest was 2014/15 with 54 cm; the biggest was 2020/21 with 104 cm (1.9 times as much). For 33% of the 534 ski areas in the United States, the leanest winter was the same 2014/15: bad winters tend to hit a whole region at once.
