Iain Martin celebrates 100 years since Chamonix hosted the Olympics.
In the century since Chamonix hosted the first Winter Olympics, the depth of the Mer de Glace has shrunk by more than 100 metres. The change is so great that in February 2024, a new gondola was opened from the glacier back to Montenvers to save skiers who have taken on the famous Vallée Blanche off-piste run from having to tackle the 580 steps that now exist back to the top.
