After the multilayer studies of the Ust-Yodarma II and the Listvenichniy Island sites in the Northern Priangariye region of the Boguchanskaya hydropower plant a big Khaita type pottery collection was discovered. It had a particular forming and decor techniques. In contrast to the «classic» Khaita pottery of the Southern Baikal ornamented with the incised lines, these vessels were using two types of counter-relief technique – indented and incised. One characteristic feature, as seen in the ornament's negatives on the inner side, is a use of the decorated fragments of the Khaita cord-impressed pottery as an «anvil» while forming vessels. Received radiocarbon dates and stratigraphic observations shows the ancient age of the Khaita vessels and document the time of the pottery formation in the region. The age is determined between 7900–5300 BP. A wide spread point out to the narrow contact of the Neolithis cultures with those of the Upper Lena and Southern Priangariye region including the Lake Baikal shores.
