Heliskiing
Heliskiing is the practice of alpine skiing using a helicopter to gain altitude instead of ski lifts. This allows heliskiers to ski off-piste from many different starting points when compared to using regular fixed ski lifts. It also allows people to ski in remote areas. Heliskiing is sometimes considered an extreme sport. The main risks are avalanches and skiing into obstacles such as trees or rocks. Helicopters used for heliskiing usually have an exterior locker in which skis and other equipment can be stored.
