Corrected for height: our long-range snow record uses weather-model ground about 700 m below the lifts, adjusted to the lifts' mid height with a simple snowpack model, so treat depths here as an estimate.

Modelled base-altitude snowfall from ERA5 reanalysis (Copernicus), EM Snow archive. The grid sits near resort base, not the summit, so treat totals as a valley-level estimate.
