After the huge snowfalls in Europe last winter, more ski areas are going in for snow farming bandwagon. Why not save it for next season?



It was first tried out in the Alps a decade ago but the idea of "farming" snow has been slow to catch on.

Now it's a growing trend as resorts recognise the financial advantages of being able to guarantee at least some snow on the ground at the start of the winter or even in the autumn.

With several poor starts to the season in recent years and last winter's bumper snowfall, it's perhaps not surprising that more ski resorts in the Alps are investing in stockpiling snow.

The latest to give it a go is one of the big French resorts.

Courchevel, part of the world's largest ski area, Les 3 Vallees, began snow farming for the first time this spring.

The impetus is a major race scheduled for December.

"20,000 cubic metres of snow have been stored under insulation panels and a special tarp on the Emile Allais racing stadium for the next Ladies Alpine Ski World Cup in December," a statement from the resort says.

"It should remain 15,000 cubic metres at the end of November "

Courchevel is unusual in using stockpiled snow for a downhill run.

Most of the resorts that have been snow farming for several years have been using the snow to create cross-country tracks or cover small areas at low altitude.

There are different techniques. While Courchevel is using insulation panels and a large tarpaulin, other areas use recycled sawdust or wood chips.

Davos in Switzerland is thought to have been the trailblazer for alpine snowfarming.

The resort has been covering a mound of snow with sawdust every spring since 2008.

The first field trials were carried out there to test the feasibility of snow farming at lower altitudes and identify the most effective methods.

They clearly showed that a thick layer of sawdust offered better protection against melting than geotextiles.

"This snow is used in the autumn to prepare a cross-country ski trail before new snow can be produced," the resort says.

"Covering the snow means that we can retain around 70-80% of the volume, which enables the resort to start the season earlier, regardless of the temperatures in autumn.

"The 4 km long snow farming cross-country skiing trail is open and can be used by both athletes and amateurs."

Davos expanded its snow farming efforts in autumn 2015 and can now store three times the volume of snow it once did for its cross-country trail in the lower Flüela Valley.

Seefeld in the Austrian Tirol is one of the leading cross-country ski areas outside of Scandinavia and will host the 2019 Nordic Ski World Championships.

The Olympiaregion Seefeld started snow farming in 2015 to improve training conditions and establish itself as a serious alternative to the Nordic countries.

It used 6,000 cubic metres of artificial snow, which it stored under a layer of wood chips to protect it from sun and rain.

Teams are able to train all day on a 1.5km long and 6 metre wide track from November.

Livigno in Italy used stored snow for the first time in August 2016 for an annual summer cross-country race - the Trofeo delle Contrade.

The snow is stored in the village during the winter, covered with a layer of sawdust and then a geothermal insulating sheet.

A recent survey by the Swiss Institute for Snow and Avalanche Research (SLF) suggests that interest in snow farming is on the rise.

  • 90% of the 100+ ski resort operators and local authorities surveyed in the German-speaking Alps and Scandinavia were familiar with snow farming
  • 49% viewed it positively, while 14% were critical
  • Roughly half who had not farmed snow were considering doing so
  • 15% said they planned to start preserving snow over the summer
The reasons given were:
  • to guarantee a minimum snow sport offering
  • to ensure a punctual start to the season
  • to compensate for the shorter snowmaking periods in autumn and early winter.

And it's not just the Alps.  In the eastern US, they've just begun a snow farming trial to create more reliable early-season snow for cross-country skiers.

An environmental geologist at the University of Vermont, Paul Bierman, is leading the project at the Craftsbury Outdoor Centre, copying some of the successful European models.

It's a small-scale trial and won't have enough stored snow for this autumn but it's hoped there will be sufficient by autumn 2019.

Snow farming is just one of the measures being taken to help deal with the impact of climate change.

Research published in early 2017 suggested that Europe's mountains could lose as much as 70 per cent of their snow cover by the end of the century.

In June 2017 we reported on a pioneering experiment in Switzerland to use artificial snow in an attempt to stop a glacier shrinking.

The experiment is apparently going well and was recently featured in an episode of BBC Radio 4's Costing The Earth.

And other projects are underway as resorts find ways to protect their lucrative snowsports industry.
