Photographer's Note

This was taken through the window of a helicopter. This is the southernmost of three craters (called Troitski) on the Maly Semyachek volcano. The volcano is three km long, and this lake is about half km wide and 140 meters deep. The temperature of the lake ranges from 27 to 42°C. The lake has a concentration of sulphate and hydrochloric acids, and a steel cane would get “swallowed” by the lake in a matter of hours. Apparently, the color of the lake changes from turquoise to green depending of the level of mineralization.

While I adjusted the brightness and contrast, I did not enhance the color at all.
