Seven month under thick ice - Mountain lake, Valais Alps, Switzerland

Work in progress

This small lake in the Swiss Alps, situated at about 2’500 m above sea level in the Canton of Valais, holds a strong stock of fish, especially Grayling (Thymallus thymallus). They manage to survive in this high elevation even with very long periods of ice covering the lake. When they ice disappears, usually in June, the Grayling enter a tiny and shallow creek to spawn.
