On Monday, February 23, Pierre Denambride, the 51-year-old head of slope safety at Flaine in Haute-Savoie, France, was killed while working on the mountain. One day later, on Tuesday night, a 41-year-old resort worker died in a separate quad accident in Flims, Switzerland, part of the Flims Laax ski area. The back-to-back tragedies have drawn attention to the use of quad bikes-often fitted with tracks or crawler systems-by ski patrol, slope safety teams, and mountain operations staff across Europe and North America.
