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

June Mountain, in United States, runs from 2,309 m at the base to 3,089 m at the top. Its mapped area is about 4.6 km across, with 36 marked runs and 7 lifts (about 27 km of piste in all).

Over the last twelve winters the ERA5 weather model gives it 463 cm of snowfall a season, 103rd of 3,069 worldwide and 23rd in the United States. It swings a lot from year to year: the biggest winter, 2022/23 (1,201 cm), brought more than 13 times as much as the leanest, 2014/15 (87 cm). March still brings 113 cm on average, close to January, its snowiest month.

Which way the slopes face

66% of the vertical on the runs descends to the north or east; plenty of the terrain faces the sun as well, so the lean is modest.

Live cameras

This ski area does not put a camera on its own slopes. What follows are nearby cameras, not the pistes themselves.

Footage remains the copyright of each operator. JAPANSNOWLINE neither stores nor redistributes it.

Some cameras here are provided by Windy.com. Footage plays in Windy’s own player; we do not store it. Windy.com

Compared with what is nearby

Within 50 km straight line. Measured the same way, so the ranks compare directly. The weather model works on cells about 30 km across; ski areas in the same cell get the same figure, and these numbers cannot separate them.

When it falls, and how winters differ

Month by month

Winter by winter

Across the 12 winters measured, the average is 463 cm, and 9 of them fell short of it. The leanest was 2014/15 with 87 cm; the biggest was 2022/23 with 1,201 cm (13.8 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.
