Ski. Freeskier Sam Favret follows the call of the ice and shows us the Mer de Glace from an entirely new perspective. For him, France’s largest glacier is basically a terrain park with natural half-pipes, kickers, and tunnels. We accompany him on his ride through a world of ice and snow, from high-speed descents to the depths of the glacier and back up again, with lots of freestyle tricks along the way.
