What is "heliskiing"

n. (alternative spelling of heli-skiing English) vb. (alternative spelling of heli-skiing English)

Heli-skiing is off-trail, downhill skiing or snowboarding that is accessed by a helicopter, as opposed to a ski lift. As early as the late 1950s helicopters were used in Alaska and Europe to access remote terrain.

Skiers board the helicopter and are carried to a landing zone on the mountain. Skis, snowboards and poles are generally carried in an exterior basket loaded and unloaded by a guide. Snow conditions on the mountains vary considerably over the course of the winter as the snow is subjected to sun, wind, temperature variation, and new snowfalls. Snow conditions change almost every day. Risks include those of back country skiing, such as avalanches and tree wells, plus those of helicopter flight. Risks are mitigated by using experienced pilots and certified guides, avalanche transceivers, avalanche air-bags, and radios.
