In this study, we analysed a 54 cm long sediment record from small lake located closely to Lake Baikal for subfossil diatom to provide an improved reconstruction of the environmental changes in the area for the past 12.4 ka. Significant changes in diatom records occurred at 10 and 4.8-4.2 ca. ka BP. The pattern of studied diatom records was close to ones from Lakes Baikal and Khubsugul.
