The Mendeleev volcano is an active volcano located in the southern part of the island of Kunashir. it belongs to the specially protected natural territories and was awarded the status of a state natural monument in 1983. It is named after the Russian chemist D. I. Mendeleev, but still people often call it the Sleeping Beauty, because it visually resembles a sleeping woman.
The slopes of the volcano – this is a real mixed coniferous-deciduous forest with patches of dwarf Siberian pine and bamboo. At an altitude of 400 m, a fumarole field is located: like water in a pot, the surface seems to boil and releases columns of steam. The release of volcanic gases through fumaroles is evidence of the transition of the volcano to an intermediate stage between eruptions or its complete extinction.
