Hans Rey, Richie Schley, and Joscha Forstreuter travelled to the Indian Himalayas. Their goal: to reach the mysterious Roopkund Lake, a glacial lake in the Uttarakhand region, famous for hundreds of ancient human skeletons at its bottom, and to ride down a sheer endless technical downhill over 3,500m/ 11'000ft vertical on trails that nobody has ever ridden before.
