Alpine skiing-Frozen In Time: Levi's farmed Snow sets the stage for Shiffrin

Mikaela shiffrin, the American slalom champion who won Saturday's first World Cup race in Finland will be using recycled snow to win.

Levi in Finland, located high up inside the Arctic Circle hosts World Cup races every year since 2004. The resort goes to great lengths to make sure that conditions are perfect. Finns are well-known for their reindeer farming, but what's more surprising is how they've mastered the art and science of snow farming. This technique could help ski resorts reduce the impact of climate change.

The temperatures in Levi have dropped dramatically and the mountains and forests are now covered with snow.

Levi was prepared even without the first big snowfall of the year, thanks to an automated system that had been tested in 2016 as a response to the 2015 cancellation of races.

Snow is piled in large storage areas before spring thaws, and then covered with geotextile and Finnfoam insulation material to prevent it from melting in summer heat. This means that 70% of the snow farmed survives.

In October, the snow is then pushed onto the slopes before it has a chance to freeze. This will form the base for the ski runs used on the weekends.

Marko Mustonen told me by phone that the winter could arrive anytime between early October and mid-November.

"Without the snow, a resort cannot function. To be ready for World Cup races we decided to harvest 15,000 cubic meters of snow 10 years ago.

It worked well and we were able to prepare a good foundation. We now farm about 40,000 cubic meters, which allows us to build the base as well as secure the racecourse. We're getting better every year at reducing the amount of snow that we lose.

Mustonen, who is a Levi employee, says that Levi has made significant investments in the most energy efficient snow-making equipment. By reusing snow from previous years, Levi can save energy and water, which are both high when producing man-made snow.

It's snowing in Levi, but the base for the course this weekend will be made from 100% recycled snow.

It could be older than that.

Shiffrin is the skier who has most enjoyed the conditions in Levi. She has won eight World Cup races there, and each win has earned her another reindeer. The first one, Rudolph, still lives on a farm near the resort.

They are Sven, Mr. Gru. Ingemar. Sunny. Lorax. Grogu. She may have to come up with another name on Saturday, as she aims for her 102nd World Cup win and 65th overall in the slalom, which is her specialty.

Mustonen added, "She visits her friends every year. Let's see if there is a new one this weekend." (Reporting and editing by Andrew Cawthorne; Martyn Herman)
