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.

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
Las Leñas, in Mendoza, Argentina, runs from 2,240 m at the base to 3,430 m at the top. Within 2.5 km of its centre the map shows 13 marked runs and 9 lifts (about 14 km of piste).
Over the last twelve winters the ERA5 weather model gives it 469 cm of snowfall a season, 97th (tied) of 3,069 worldwide and 4th in Argentina. It swings a lot from year to year: the biggest winter, 2023 (1,034 cm), brought more than 5 times as much as the leanest, 2016 (196 cm). Snowfall days average −4.7°C at mid-mountain, and its snow-quality score ranks 1st of 13 in Argentina.
Counted from the marked runs and lifts on the map, within 2.5 km of the centre of the ski area. These are not the resort’s own published figures.
Source: OpenStreetMap (ODbL 1.0). How finely ski areas are drawn varies by region, so treat the counts as indicative. Difficulty uses the European grades, which do not map onto North American green / blue / black.
This ski area does not put a camera on its own slopes. What follows are nearby cameras, not the pistes themselves.

Modelled from weather data the same way at all 3,069 ski areas we cover. These are not the resort’s own published figures.
The tick marks the median across every Japanese ski area we measure. All four bars run the same way — longer is better.
The quality score leaves out how much snow falls (it uses temperature, frequency, rain and wind).
The most snow falls in June. September brings 88% of July’s snowfall. That is a gentler fall than the median for ski areas in Argentina (61%). In amount, September brings 79 cm, more than the median of 56 cm.
Across the 12 winters measured, the average is 469 cm, and 8 of them fell short of it. The leanest was 2016 with 196 cm; the biggest was 2023 with 1,034 cm (5.3 times as much).
Snowfall each winter (June–September total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
