Crater lake – one of the greatest creations of the sorceress nature. Most of them were formed millennia ago from rain and glacial water in natural reservoirs, formed due to volcanic eruptions. Landscape these ponds provide fantastic, therefore, it constantly attracts numerous tourists. One of such natural attractions of our planet is a beautiful crater Lake (The Crater Lake) – that is, literally, “Crater lake”, which is located in the U.S. state of Oregon.
This reservoir has an ancient history – he appeared more than 7700 years ago, after the last eruption of the mazama volcano (Mount Mazama). Over time, they formed on the site of the eruption, the Caldera is a huge depression with almost straight vertical walls and the bottom deep was filled with water and formed lake, leaving on the surface only a few small objects of volcanic origin. One – Hex island (Wizard Island), and today dominates the clear waters of the lake. All the beauty of natural attractions just a professional photographer .
Crater lake is located at an altitude of about 2400 m above sea level and has a fairly large dimensions: 8 by 9.6 km Maximum distance from the surface to the bottom of this reservoir reaches 594 m, making it the eighth place in depth world and second in North America.

Kelimutu volcano is located on lost in the ocean island of Flores, which belongs to the Small Eastern Indonesian Sunda Islands. Since the island is far removed from the mainland, tourists visit it not so often, Yes, and, frankly, there is almost no infrastructure. The last time the volcano erupted in the last century, in 1968, and doesn’t give any signs of activity. But in the last eruption in the magma formed coldera, which were a kind of cups, which collect water from precipitation.
Today flying over the island can be clearly seen from the aircraft with three bright turquoise spots – this is the famous lake Kelimutu. What are they famous for?
The fact that lake Kelimutu is constantly changing colour. Turquoise lake over the year could turn into turquoise, then after a certain time become red or green. Due to this, however, the presence in water of various minerals. It is the chemical relationship of these components and leads to a dynamic change of color of the water. Well, for example, green lake suggests that, in reaction into hydrochloric and sulphuric acids, the red tint of the water indicates the interaction of hydrogen sulphide with iron.
The local aboriginal people, who belong to the tribe of Leo, there is a legend about Kelimutu. They say that the lakes are inhabited by the souls of the dead. Continue reading
Dangerous the lake is at the top of the volcano Small Semyachik. Namely, in the crater of the name of the Trinity. It attracts tourists with its amazing color — with height of bird’s flight in Sunny weather, overlooking the bright turquoise lake surrounded by black earth. This color give the lake the smallest particles of sulfur that are released into the water from the volcano. If you look at the lake from the surface of the earth, it is impossible to believe that it looks turquoise on top. From some angles the pond seems to be just muddy. The diameter of the lake is small — only 500-600 meters.
The Semyachik volcano is considered to be valid, some scientists believe that this lake was formed as a result of one of the eruptions. The water temperature here is around 30-40 degrees, but the lake gradually cools down. In some winters the surface is fully covered with ice and snow.
In the crater of the Trinity on the shore there is a small black beach, but swimming there is deadly: dissolved in water acid eat through even metal. Prolonged exposure near a lake without a mask can also harm the health. However, tourists are regularly organized not only helicopter tours over the volcano, but Hiking tours on the lake — and even with the descent into the crater to the shore.
