But the effects of the massive artificial snow output are worrying scientists. "Artificial snow melts two to three weeks later (than normal snow)," says Christian Rixen of the Swiss Federal Institute for Snow and Avalanche Research. Adding to the worry is the fact that artificial snow melt contains more minerals and nutrients than regular melt water. One consequence of the different composition is an alteration of the natural ground covering, as plants with higher nutritional requirements suddenly begin to dominate.
