- Аннотация: The isotope composition and hydrochemical properties of the Late Pleistocene ice wedges in the outcrop of fl at side of Kular Ridge located in the western part of Yana-Indigirka Lowland have been analyzed. It has been established that variations of the δ18О values in the ice wedges (varying –32.6 ‰ to –31.0 ‰) do not exceed 1.6 ‰. The mean winter and mean January temperature reconstructions have been carried out by means of the palaeogeocryologyical studies of the oxygen stable isotopes contained in ice wedges. In the Kular Ridge area, the mean January air temperature in Late Pleistocene was by 7 °C lower than the current. Besides, the lowest mean winter temperature referred to the 37–32 ka BP.
