Boreal is the site of the first North American
demonstration of a relatively new technology called Snow factory. The process
parallels that of an industrial icemaker — essentially, a large-scale version
of the icemaker in the door of many household refrigerators.
An ice-maker takes water chilled with a heat
ex-changer and sprays it onto a surface. The cubes are created by imposing the
ice onto a grid. In a unit about the size of a trailer, such as the type pulled
by 18-wheeler trucks, Snow-factory uses the same process to produce flat flakes
that are collected on a panel and fed into a conveyor belt. The flakes are then
blown through a pipe up to 600 feet (183 meters) long to the desired location
on the ski slope. [Photos: The 8 Coldest Places on Earth]
