Especially in autumn, when there hasn’t been much snow yet, or in spring, when the snow is already melting, the slopes that have been made with artificial snow can be easily recognized. The whole landscape is green and brown except for a few white stripes.
Artificially produced snow consists of water that is extracted from nearby streams and (storage) lakes and is pressed through the fine nozzles of snow machines at high pressure. This produces tiny droplets, which, when cold, freeze as soon as they come out of the nozzles. As grains of ice they fall to the ground. The drier and colder it is, the better snowmaking works.
