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.

Score breakdown
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
Three Summits, in United States, runs from 800 m at the base to 1,183 m at the top. Its mapped area is about 5.6 km across, with 103 marked runs and 20 lifts (about 43 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 531 cm of snowfall a season, 73rd (tied) of 3,069 worldwide and 17th in the United States. It swings a lot from year to year: the biggest winter, 2017/18 (737 cm), brought more than 5 times as much as the leanest, 2014/15 (134 cm). December brings as much snow as January here (157 and 130 cm on average).
The nearest city of any size is Seattle, about 72 km away in a straight line.
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.

Which way the slopes face
84% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

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

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.
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
Month by month, the most snow falls in December. March brings 79% of January’s snowfall. That is in line with the median for ski areas in the United States (85%). In amount, March brings 103 cm, more than the median of 30 cm.
Winter by winter
Across the 12 winters measured, the average is 531 cm, and 7 of them fell short of it. The leanest was 2014/15 with 134 cm; the biggest was 2017/18 with 737 cm (5.5 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.
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
