Snowfarming in Bessans
Reusing snow from one winter to the next
It's no scoop: at the end of winter, snow... melts. Unless... you preserve it! There's no need to equip yourself with giant refrigerators to make the white gold last. A 100% natural, regional material is more than enough: by covering the snow with sawdust, it resists heat and can be preserved for many months. This is the "snowfarming" technique, which makes it possible to use snow from one winter to the next, insulating it from the ambient air and summer sun thanks to a clever mixture of sawdust.
In Bessans, between January and March 2024, 19,300 m3 of snow were stored near the biathlon stadium. Chosen for its naturally cool, shady environment and proximity to the area to be snowed, this location facilitates snow conservation. At the beginning of November, if weather conditions are favorable (cool temperatures in particular) and on the advice of a weather expert, the layer of sawdust is removed. The snow can then be spread out to form a 2 to 3.3 km loop. Amateur and professional skiers can then enjoy the pleasure of sliding and shooting on the biathlon stadium. Every autumn, some of the world's best come to Bessans to take advantage of the snow to finalize their cross-country or biathlon preparations.
The "snowfarming" trail is then extended and completed by snowfall until the resort is fully open.
