Snow sculpting competitions last two-and-a-half days. Teams spend most of that time outside in intense winter conditions. (They can warm up in heated tents.) Sometimes Team Kwe works through the night to finish their sculptures on time. The coldest temperature that the team competed in was -60 degrees Fahrenheit!
But the weather can change a lot throughout each event. That’s part of what makes snow sculpting challenging, the team explains. Changes in temperature, precipitation, sunlight, and wind affect the consistency of the snow they’re working with. When it’s really cold, the snow becomes hard and difficult to sculpt. Warm snow can be molded like mashed potatoes. “Mother Nature is our fourth teammate,” says Friedli.
Math helps Team Kwe’s members plan their sculptures and tackle problems. First, they draw a grid on the 8-foot cube of snow to visualize where each part of the sculpture will be. They mark each spot, like plotting points on a coordinate grid.
Next, they shape the block using hand tools like saws, chisels, and more. While sculpting, each team member is always thinking about the shape and the weight of the snow left behind. If they carve out too much in the wrong place, their sculpture might fall over! When time’s up, a panel of judges chooses the winning sculpture.
