The Vostochny Thermal Field in the northern part of Uzon caldera contains a large number of thermal lakes and springs. A narrow area 200-300 m x 5 km contains fumaroles, boiling hot springs with colonies of blue-green algae, and mud pots. The northern caldera wall forms the ridge in the background.
