In the asymmetrical valleys of northern Yakutia, thick covers of slope deposits occur, forming rhythmic horizons in the upper valley segments related to periodic changes in climate and slope dynamics. Solifluction deposits, poor in organic remains, developed during cooler phases of intensive slope activity and contain numerous ice lenses, ice veins and deformed peaty layers with plant remains. Three Würmian phases of increasing climatic severity have been distinguished in northern Yakutia, correlated with the Zyryan and Sartansk stadials, whereas warmer oscillations correspond to interstadials and the postglacial period.
