Ski Ostružná - Řetězárna
Ski Ostružná - Řetězárna is a ski area in Czechia. It sits at about 875 m above sea level. The mapped ski area is about 0.6 km across, corner to corner. The map shows 3 marked runs and 1 lift inside the ski area, totalling about 0.9 km of piste. Averaged over the last twelve winters, the ERA5 reanalysis gives it 143 cm of snowfall a season, 1761st (tied) of the 3,069 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. 32 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.
