The Weissfluhjoch (2,693 m (8,835 ft)) is a summit southeast of the Weissfluh (2,843 m (9,327 ft)) situated in the Plessur Range in Graubünden, Switzerland. Since 1932, a funicular railway (the Parsennbahn) leads to its summit from Davos.
On the Weissflujoch, there used to be several laboratories of the Institute for Snow and Avalanche Research, a division of the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL).[2] However, while there is still a test site at the location,[3] the institute building was sold to Davos Klosters Bergbahnen Ltd in 2019.[4]
