Reuters: This Austrian ski resort is using snow that has been farmed from last winter to give skiers a chance to hit the slopes during unpredictable climate.
In the province of Tyrol, climate change makes the winter season increasingly difficult for ski resorts to plan. To combat these weather changes, snow is stored over the summer under wood chippings that can then be used for the Leutasch cross-country ski trail.
Elias Walser is the CEO of Seefeld’s Tourism Association.
"So, we prepared this pile which you can see in the background and is from last winter, at the height of winter, when it's really, really cold. That's when we produce snow and also push the snow from the cross-country ski trail together. And this pile of snow is then covered with wood chips in the spring. We put about half a meter of wood chips on top, and this half-meter of wood chips is enough to keep the snow in place throughout the summer. It sinks in, it compacts. Around 10 to 15% of the snow melts, but the rest is preserved. And then this pile is covered by the wood chips until the beginning of November. And then, when the temperatures are right, we put it on the cross-country ski trail."
Leutasch has been using this technique since 2015 with more than 10,000 cubic meters of snow kept under wraps over the summer. That could fill four Olympic-sized swimming pools.
"So we notice climate change. Winters are no longer as predictable. The natural snow cover is becoming a little less. And that's why we decided many, many years ago to make snow for some of our cross-country ski trails."
The cross-country snow trail on the Tyrolean high plateau is over a mile long and takes the resort four days to prepare. Despite mild temperatures and green forests still visible, cross-country skiers can flex their muscles from mid-November.
"The advantages are that you can plan when the cross-country skiing season starts. Otherwise, in some winters you have no problem cross-country skiing already in November and then there have been winters where we can only open the cross-country ski trail just before Christmas. So this gives us planning security."
