Camel’s Hump is white with snow, and Vermont ski slopes begin opening this month. That means it’s Miller time — Warren Miller, that is. This year’s film carrying the name of the grandfather of skiing and snowboarding epics features professional Norwegian freeskier Dennis Risvoll in Warren Miller’s Face of Winter. Like all Warren Miller Entertainment films made since 1950, it boasts remarkable location footage, serious shredding and a voice-over that guides viewers through arctic thrills. The amiable 31-year-old Risvoll treks through knee-deep powder, schusses past snow-laden pines and flips above precarious drops at Red Mountain Resort in Rossland, British Columbia.
