The spatial and temporal variability of the thermal resistance of snow cover has been examined for a number of areas of the Krasnoyarsk region. The correlation between the snow cover thickness and its thermal resistance and the depth of ground freezing has been carried out. Analysis of the influence of the parameters of snow cover and ground on the depth of ground freezing has been given. The influence of the texture of snow cover and layers of deep hoar on thermal resistance has been assessed. It has been demonstrated that the value of thermal resistance can be 1.5 times lower than the real one if the stratigraphy of snow cover is not taken into account.
