While most people look at Crevasses as their worst nightmare while venturing out on the mountain, Sam Favret uses them as a source of terrain while skiing. In this video, Sam shreds the mythical Mer de Glace, at the heart of the Mont-Blanc mountains in France. The Mer de Glace (Sea of Ice) is the largest glacier in France, 7km long and 200m deep and is one of theย largest attractions in the Chamonix Valley. The ice and glaciated snow is so sick, along with Sam’s skiing.
