Copper Mountain is a ski area in United States, on slopes between roughly 3,410 and 3,410 m. Its mapped area is about 6.9 km across, with 153 marked runs and 23 lifts (about 115 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 157 cm of snowfall a season, 1,578th (tied) of 3,069 worldwide and 181st in the United States. Its winters are fairly steady; even the leanest, 2025/26 (113 cm), reached 72% of the average. December brings as much snow as January here (39 and 35 cm on average).

Elevation range is estimated by sampling points across the ski area.
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.

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
86% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

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. Ski areas a few kilometres apart share a weather grid cell and can return the same figure.

| Ski Cooper | 17 km | 146 cm | 1714 |
| Keystone | 22 km | 161 cm | 1527 |

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 43 cm, more than the median of 30 cm.
Winter by winter
Across the 12 winters measured, the average is 157 cm, and 5 of them fell short of it. The leanest was 2025/26 with 113 cm; the biggest was 2016/17 with 203 cm (1.8 times as much).
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
