The Caldera of Uzon volcano description
The Uzon Caldera is a unique area manifestation of modern volcanism. The Caldera of Uzon volcano is on the Kamchatka Peninsula on the territory of the Kronotsky reserve, South of Kronotsky lake. This is the place that shaped a unique symbiosis of wild nature and volcanism.
The Uzon Caldera was formed about 40 thousand years ago on the site of a huge volcano destroyed near a powerful explosive eruptions. Caldera is a massive bowl-shaped depression about 150 sq km, surrounded by steep ledges, the height of which ranges from 200 to 850 m.
The hydrothermal system of the Caldera of volcano Uzon is one of the most powerful on the Kamchatka Peninsula. On the territory of the width of 200-350 m and is located more than a thousand thermal springs in various sizes and shapes, a large number of thermal lakes, the outputs of the gas-steam jets, mud volcanoes and mud pots. There are also outputs of Seltzer.
The Uzon Caldera is a unique place where there are a variety of existence of young volcanism of different composition, the products of glaciation, as well as connection with sulfatar fields with native sulphur deposits and accumulations of hydrothermal altered rocks of all colors.
Of particular interest to scientists are the amazing lakes (Central and Bath), as well as the chemical composition of the soil and water of the Caldera. Thermal waters are characterized by high content of arsenic, mercury, antimony and copper. Noteworthy is the fact that in the thermal springs of the Caldera of Uzon volcano is inhabited by unique microorganisms such as archaea belonging neither to the bacteria nor algae. Archaea living in boiling water, where oxygen replaces them with sulfur and hydrogen sulfide.
One of the main attractions of the Caldera mud pot reads “Sculptor”. Its name speaks for itself. Every couple of seconds mud pot “model” interesting and original education, which in their form resemble roses. Because of continuous geological processes in 2008 was a new geyser “Muddy”.
