It looks like a lake in the mouth of an old volcano

Wind sounds on a beautiful lake, high in the mountains. Of course, this is not the mouth of a volcano, but it looks very much like it from a certain angle, thanks to the high mountains around and the weather conditions that day. This is an artificial reservoir in a mountain gorge, created by people to cool industrial water from the enterprise. This organization has long been discontinued, and the lake remains as a local attraction.
