The effect of the redistribution of snow cover on the temperature dynamics of soils and the formation of frozen strata is demonstrated in an example of an industrial site under design for the Yamsoveisk gas field. The multiyear-frost depth of soils for which the heaving of pile foundations occurs is estimated, and recommendations are given for their heave protection. It is demonstrated that in southern regions of the cryolithic zone, it is impossible to design structures without special geocryological prediction, even in those cases when explorations do not detect the presence of frozen soils at the production site. This paper was written on the basis of studies financed by the Russian Fund for Fundamental Research (Project No. 94-05-16195-a).
