Study of the sites dated to Pleistocene-Holocene boundary in the northern area of Krasnoyarsk water reservoir

In the summer of 2015, the continuing archaeological study was conducted on the sites dated to Pleistocene-Holocene boundary and found in 2014 in the Northern area of Krasnoyarsk water reservoir (Balakhtinskiy district of Krasnoyarsk region). The test pits and small excavation areas were laid out at the Byuza II and Troitskaya sites and gave the material in situ. Archaeological material from the cultural layer is identic to the surface artifacts from the shoreline overwash. The stratigraphic situation of the both sites allows dating the cultural layers of Byuza II and Troitskaya sites to Early Holocene and Final Pleistocene respectively. The typologically closed to Byuza II Early Holocene industries is unknown for Middle Yenisei river basin at this moment. Archaeological complex of Troitskaya site has the analogies among the sites of Kokorevo archaeological culture. Evaluation of their current condition including the incline of the modern surface, the elevation of the primary cliff and width of the secondary cliff allows proposing that some perspectives of the further research can be realized at the Byuza II, Troitskaya and Cheremushki II sites only. Cheremushki I and II sites are destroy already. At this moment previously exposed material moves from the surface of the secondary cliff to riverside area that supposes the further blurring and depositing into the clay. The investigation of the area of Krasnoyarsk water reservoir this year demonstrates that all Middle Yenisei Paleolithic sites can be destroyed in the nearest time. The extant objects with cultural layer in situ represent just the inner marginal areas of the ancient settlements.
