Abstract : In practical terms one of the most important characteristics in the field of distribution of rocks frozen for many years is the strength of the seasonally thawing layer. Its magnitude often determines both the conditions for excavating and the construction of parts of various equipment sunk into the ground. Areas that have not been studied are usually characterized by analogy to adjacent regions for which there are corresponding data. In this regard, essential inaccuracies can arise because it is not always possible to take the natural peculiarities of the area in question and the zonal changes in the depth of the seasonal thawing into account. The mapping of this characteristic of frozen layers has been called upon to play a sizable role in improving the accuracy of predictions. (Author)
