The taiga zone of the Northern Angara region in archaeological terms has long been understudied. Intensification of the industrial development of this territory allowed to organize large-scale archaeological excavations, especially in the flood zone Boguchanskaya HPP. In 2013 there were conducted the excavations of Generalov site in the construction zone of the main pipeline "Kuyumba-Taishet" on Tchouna river (border of Irkutsk and Krasnoyarsk region) to the south of lower Angara. Archaeological material is incorporated into the upper part of the thickness of aeolian deposits of Holocene age. We allocated 4 level findings (cultural horizon): 1 c. h. – Early Iron Age, the Middle Ages 2 c. h. – Late Neolithic, Bronze Age 3 c. h – Neolithic 4 c. h – Early Neolithic. The findings are presented by the objects of stone, ceramic vessels, a few small faunal remains, a fragment of metal products. We revealed several complexes, which can be attributed to the ritual ones: stone construction, burial with Ust’-Belaya type vessel, treasure stone tools. The resulting materials and data showed that the Holocene culture of contact zone in southern Northen Angara region is part of a single community of cultures of the Neolithic – paleometal of the Central Siberia.
