We have found what the largest glacier deposits on the Baikal shoreline, so-called Tompuda end moraine, formed in two stages. The first stage occurred until ca. 12 cal ka BP; then, there was a short pause. The second stage ended by 9.5 cal ka BP. Azarova glacier (Kodar Ridge) retreated upwards the Kodar Ridge by ca. 11 cal ka BP. It may indicate that the B{\o}lling-Aller{\o}d warming was very evident, and it was a trigger for these deglacial events in East Siberia. It is most likely that “remains” of the Late Pleistocene glaciers were cardinally shrunk or fully disappeared during the Holocene Thermal Optimum in the southern part of East Siberia. Climate conditions were suitable for glacier formation after 3 cal ka BP. However, if there were new glaciers in the Middle Holocene, their sizes were likely to be less than 1 km 2 . For this reason, these glaciers should have completely melted during the Roman and Medieval Warm Periods. It is most likely, small glaciers observed at present in the south of East Siberia were mainly formed during the Little Ice Age. ",
