Two exposures of unusual ice-wedge sediment complexes are described from the Upper Kolyma region. The sediment is peaty loam with a rock debris content of more than 30%. The oxygen isotope composition of the ice-wedges and radiocarbon age of the enclosing sediments allow one to reconstruct palaeo-facial and palaeo-climatic information. The oxygen isotope data are interpreted in terms of mean winter temperatures. The mean winter temperatures for most of the ice-wedge forming period were lower than modern ones by 5–6 °C; and mean January temperatures were lower by 7–9 °C. © 1998 John Wiley & Sons, Ltd.
