Fig.22 - At Caumasee (Lag la Cauma) in Flims, 3,260 ft (995 meters) above sea-level. "Cauma" means Siesta (a break from work, taking a nap in the afternoon). The turquoise-blue color of the lake is caused by light scattering by suspended particles present in the water. Nikon Z6, Nikon Z 24-70mm f/4S lens (October, 2021).
