Big Rock Mountain

8 / 100 Powder Score
Thin ☁️ Official site

Big Rock Mountain is a ski area in United States. It sits at about 318 m above sea level. The mapped ski area covers about 1.7 km². Within 2.5 km of the centre, the map shows 36 marked runs and 4 lifts, totalling about 11 km of piste. Over the last three winters the ERA5 reanalysis gives it 135 cm of snowfall a season, 1752nd (tied) of the 3,112 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. 10 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.
