Abstract. The upper Quaternary deposits of the West Siberian plain contain traces of cryogenic phenomena and processes, which are preserved in the form of post-cryogenic formations. Thanks to the information hidden in the details of the structure of these structures, as well as in their relationship with the host strata, it is possible to reconstruct the conditions of their formation in order to include the stages of freezing and thawing, accompanying them, in the general stratigraphic scheme of the region.

Keywords: post-cryogenic formations, pseudomorphoses, cryoturbations, cryogenic involutions, West Siberia
