Sébastien de Sainte Marie skis steep Swiss trilogy

36-year-old Swiss steep skier Sébastien de Sainte Marie reports about an interesting trilogy of steep ski descents between Davos and Arosa: West Face of Schiesshorn (2605m) and Tiejer Flue (2781m) on his own, and the North Face of Chüpfenflue (2658m) with Michal Dzian. These descents came about thanks to the 'exceptional winter' and while it is unclear whether they are first descents, they are certainly very rare indeed.
