Abstract. There are presented materials in respect to the Quaternary paleocryological development of the area in the north of the West-Siberian Plain. Data demonstrating wide distribution of polygonal-wedge structures in the region are elucidated. The structures represent polygonal ice wedge pseudomorphs and initially ground wedges. The first developed in the terminal phase of the Pleistocene in the end of MIS-2, and are the successors of the epigenetic polygonal ice wedges which cut the Karga, MIS-3, alluvial thickness, whereas the second formed in the syncryogenetic alluvial deposits in the course of MIS-3. All of that shows non-glaciated development of the region in the cryochrons and thermochrons which are similar to MIS-2 and MIS-3. Keywords: permafrost, paleocryogenesis, polygonal-wedge structures, north of West Siberia
