THE FIFTH CULTURAL LAYER OF THE USHKI SITES: TOWARDS THE QUESTION OF THE FINAL PALEOLITHIC OF KAMCHATKA
The paper considers some problems of the terminal Upper Paleolithic in Kamchatka in the light of tephrochronological evidence. The correlation of new dates obtained for cultural layers with their inventory and reference ash horizons confirms the validity of N. N. Dikov’s concept of Holocene Paleolithic. The catastrophic volcanic eruptions that took place in the beginning of the Holocene became the crucial factor of the abrupt culture change on the peninsula.
