Abstract : A critical analysis is given of the three theories regarding the hardening of the snow cover - regelation, molecular, and sublimation - thermodynamic. Special attention is given the third theory which gives the most satisfactory explanation of a series of properties characteristics of the snow cover. New data are presented in confirmation of the presence of the sublimation process within the snow and substantiating the importance of water vapor.
