Cherskiy Volcano
Tunkinskaya Valley is characterized by a great number of extinct volcanoes. Volcanic activity took place here about 10-15 thousand years ago, in the late Ice Age. Cherskiy Volcano has preserved its original view better than other volcanoes in the valley. Its hight above the lava bed level reaches 100-200 metres, diameter of the crater is 80-100 metres. The locals call this volcano Khara-Boldok. Volcanic hill is presented by scoria conglomeration of irregular shape and is comprised of fine tuffs. A spring welling out of the volcano foot doesn't freeze over even in winter.
