Big Sky Resort opened 854 acres of terrain, including advanced and expert slopes on the Challenger Chair and the Lone Peak Triple. A total of seven lifts cranked into operation for the Thanksgiving weekend opening. The upper mountain terrain boasts completely natural snow that mostly fell in October. "We got pasted with a perfect storm early in the week, followed by days of ideal snowmaking temperatures for the lower mountain," said sales and marketing director, Meg O'Leary. "Black diamond powder skiing in November, what else can go right." Only Grand Targhee to the south has more terrain open in the Rocky Mountains from New Mexico to Montana.
