Baikal Volcanoes The research shows that several thousand years ago there were active volcanoes on the territory adjacent to Lake Baikal. Volcanic eruptions were connected with deep breaks in the earth’s crust which reached the melted layer, the magma. The magma poured onto the surface through the clefts, forming lava fields. In the course of time the clinker destroyed under the influence of the wind, water and temperature differences forming mountains of fantastic form not resembling volcanoes. The oldest eruptions were characteristic of the Tunka valley, the Khamar-Daban mountain range, the Dzhida and the Oka districts as well as the Vitim plateau. In the Tunka valley the craters of the extinct volcanoes were destroyed, covered with vegetation and now they resemble low sopkas (hills) against the background of the pointed peaks of the Sayan mountains. In the mountains of Khamar-Daban, in the Stanovoye upland there are cone-shaped volcanoes. Their craters are destroyed and sometimes filled with water (Urunduchi volcano). According to G.G. Galazi’s assumption, there are also volcanoes under the Baikal water. The scientist gives such facts about it: igneous rocks (volcanic tuffs) can be found not only on the shore of the lake but also on the Ushkanyi islands, near Cedar capes.
