The article discusses data on the lithological composition of bottom sediments from two small lakes – Lake Lavkozero and Lake Gangozero, located on the Zaonezhsky Peninsula, within the area of the Onega Ice Lake. In the recovered sediment sequences from studied lakes, two sediment units from top to down have been recognized: Holocene gyttja from small isolated lakes and Late Pleistocene sediments from the Onega Ice Lake, which are represented by varved clays and silts. Based on lithological data, a “pink horizon” of varved clays was identified. It is similar to one which found in the sediment section of the Unitskaya Bay in Lake Onega. The absolute hypsometric position of this “pink horizon” was determined based on the elevation levels of the lakes under study.
