We are going to fly over the most famous volcanoes of central Kamchatka by helicopter. The weather is nice though it is always foggy over Kamchatka. On this photo is Karymskaya hill, it is an active volcano.
It is 1536 m high (5039 ft). Its top is a right truncated cone. It constantly emits hot gases. It is located in the caldera of the ancient volcano (with the diameter of five km (three miles).
There was time when people were not afraid of bathing in the Moscow river. The water was clear enough and people were less demanding than today. 50-70 years ago they didn't think much about ecology or treatment
plants, they polluted the river and it was considered to be normal. Boys swimming opposite the Kremlin were not uncommon. It was a good time. If they had a beach near the Kremlin today, would you plunge?
