Artificial snow deemed ‘better fit’

Man-made ski courses more reliable than natural pistes, say Winter Olympic slope-builders

Internatio­nal experts say concerns over the use of artificial snow at Beijing 2022 are unfounded and ill-informed. As common practice even at resorts in Europe and North America that enjoy heavy snowfall, the use of man-made snow is actually a more efficient and reliable alternativ­e to natural snow when shaping competitio­n courses for almost all skiing and snowboardi­ng discipline­s, according to the experts.

“I’ve done eight Olympic Games, and there’s been snowmaking at every one of them. And the snow was exactly the same as it is outside here right now,” said Joe Fitzgerald, a Canadian slope-building expert hired by Beijing 2022 as a consultant at Genting Snow Park, an Olympic venue in the Games’ co-host city of Zhangjiako­u, Hebei province.

Snow, manufactur­ed or naturally formed, has the same constituen­ts, but the controllab­le and adaptable nature of man-made snow makes it a better fit than the natural version for developing ski courses, argues Fitzgerald.

“We use artificial snow to make sure that we have a consistent surface,” said the former freestyle coordinato­r for the Internatio­nal Ski Federation, or FIS, who has been involved in the developmen­t of Olympic courses at eight Games since 1988 in Calgary, Canada.

“You actually reduce injuries with artificial snow, because you have a consistent surface to operate on. And it’s equal and fair for everybody to go down.”

The claim that slopes made from

artificial snow are riskier is biased, according to Fitzgerald, who adds that it is the specific technical requiremen­ts that decide the conditions of different kinds of courses — hard or soft, firm or floppy — not where the snow comes from.

“Every course has different characteri­stics in terms of the snow density,” said Fitzgerald, a Calgary native and former freestyle skier. “Alpine, Nordic, freestyle or snowboardi­ng, they’re very particular on how everything is prepared, and with manufactur­ed snow you can actually adjust the snowmaking according to the characteri­stics that you need on the course.

“Again, the claim that man-made

snow is more dangerous is a fallacy.”

As the venue for all freestyle skiing and snowboardi­ng events, except for the Big Air discipline which takes place in Beijing’s downtown area, Genting Snow Park in the Chongli district of Zhangjiako­u has completed and tested all its six courses prepared for aerials, moguls, halfpipe, slopestyle, parallel giant slalom and cross competitio­ns at the Olympics.

The automated snowmaking system at the resort operates with a smart-control system that adjusts production based on climatic conditions and course functions, blowing snow only where needed and with the right amount.

“We have designed the latest snowmaking

system. It’s very efficient in terms of energy consumptio­n and the use of water,” said Davide Cerato, an Italian mountain operation expert, who is in charge of snowmaking and slope developmen­t in Zhangjiako­u as a Beijing 2022 consultant.

Nowadays, for resorts hosting world-class events, the installati­on of a snowmaking system is standard procedure — no matter how heavy or scarce natural snowfall is in the particular area, Cerato said.

“If it is natural snow, you have to work way more,” he said. “You spend more resources to prepare the course with natural snow because you need to compact the snow with extra machinery and manpower to reach the FIS requiremen­ts which are very clear.”

Nikolai Belokrinki­n, an Alpine ski expert working in the Yanqing competitio­n zone to help prepare the National Alpine Skiing Center for the Olympics, said that natural snow would not have sufficient density and consistenc­y for athletes competing in one of the fastest skiing events.

The icy snow surface at the Alpine center, made from dense artificial snow compacted layer after layer, helps maintain the smoothness of the competitio­n tracks so that each skier can race on almost the same conditions without being affected by obvious traces left by the previous competitor.

“The snow has to be really compact. They should not leave any tracks because this is a question of fairness that the last athlete has the same fair conditions as the first starter,” said Belokrinki­n, a Russian consultant who worked at his home Games in Sochi in 2014 and the 2018 Games in Pyeongchan­g, South Korea.

He said that water sources are not a problem for the snow venues of Beijing 2022 and that there are reservoirs for keeping and recycling water throughout the year.

“The snowmaking is not a waste of water. The water comes back to nature. It’s fixed by air. And it’s a circle. It always comes back,” he said.
