Uzon Caldera is a unique area of ​​contemporary volcanism. Uzon Caldera on the Kamchatka Peninsula is located in the famous Kronotsky Nature Reserve, south of the Kronotsky lake. This is the place where form a unique symbiosis of wildlife and volcanism.

Uzon caldera was formed about 40 thousand. Years ago on the site of a huge volcano destroyed by a number of powerful explosive eruptions. Caldera is a massive bowl-shaped basin area of ​​about 150 square meters. km, surrounded by steep ledges, whose height ranges from 200 to 850 m.

The hydrothermal system of the caldera Uzon - one of the most powerful on the Kamchatka Peninsula. On the territory of 200-350 meters in width is more than a thousand hot springs of various sizes and shapes, a large number of thermal lakes, output steam-gas jets, mud volcanoes and mud pots. There are also outlets of mineral water.

Caldera Uzon - a unique place at the same time there are various manifestations of the young volcanism of different composition, food freezing and solfatar field with deposits of native sulfur and accumulations of hydrothermal altered rocks of all colors.

Of particular interest to scientists are amazing Lake (Central and bath), as well as the chemical composition of the soil and water of the caldera. The thermal waters are characterized by high levels of arsenic, mercury, antimony and copper. Notable is the fact that in the thermal springs of the caldera Uzon inhabit these unique organisms like archaea, do not belong to the bacteria or algae. Archaea live in boiling water, where it replaces the oxygen sulfur and hydrogen sulfide.

One of the main attractions of the caldera read a mud pot "sculptor". Its name speaks for itself. Every few seconds, a mud pot "sculpts" interesting original education, which by its shape resemble roses. Because of continuous geological processes in 2008 it was formed a new geyser "cloudy."

Thanks to the mild climate and warm waters around here plenty of birds fly for nesting. In April-May Uzon massively visited by bears.
