Coldest wind chill I hit was in Jan with a -55 at Sunday River. We were on the Barker Chair approaching the landing tower when a gust of tremendous strength blew our chair sideways high, the chair in front of us slammed into the irons of the tower high speed disengagement and dented the tower. We were the last chair luckily and let off as the lift slowed to a stop and were able to get off. That dent is still visible. The wind actually stopped our down hill descent on a steep run as we went down. Incredible cold and wind combo. Took this pic off a video posted last winter. Circled area is the damage still visible.
