Happy Jack Winter Trails
Happy Jack Winter Trails is a ski area in United States. It sits at about 2,624 m above sea level. The mapped ski area covers about 4.1 km². Over the last three winters the ERA5 reanalysis gives it 77 cm of snowfall a season, 2494th (tied) of the 3,112 ski areas we measure worldwide. The model runs well below what resorts report, so the ranking is the meaningful part rather than the centimetre figure. 4 other ski areas lie within 120 km. Snow figures and the Powder Score are recalculated every day.
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.
