Cédric Gras and Matthieu Tordeur set off to cross the world’s largest mountain glacier, the Fedchenko in the heart of the Pamir, to explore this totally forgotten area. It takes a week’s walk at an altitude of 4,000m, crossing glaciers, passes and dangerous rivers to reach the banks of the giant glacier, 77km long, with a mass one and a half times that of all the glaciers in the Alps combined.

With a Tajik team, led by Anatoli, a Tajik guide, the only one who knows the route, they will encounter unexpected obstacles. Since the first expedition in 1928, nothing has changed, nature has remained intact. They will discover a timeless place, the former Gorbunov weather station, built in the 1930s and abandoned for 30 years.
