Introduction The topic of methods of excavation of monuments located in the permafrost zone, or in the permafrost zone, opens up significant prospects for the exchange of opinions and experience. The cryolithozone is very extensive and, in addition to the Arctic and Subarctic, is found on the territory of Mongolia, Northern China, and Kazakhstan. In its southern limits, it does not have a continuous distribution and is represented by spots of different area, thickness, and origin [Geocryological Map of the USSR..., 1997; Circum-Arctic Map..., 1997; Yershov, 2002; et al.], growing from south to north from the first tens to hundreds of meters in the high-altitude regions of the planet (Fig. 1). Permafrost rocks are usually associated by most archaeologists who are not directly involved in working in the permafrost zone with seasonally frozen soils, which can be observed everywhere in winter. It should be noted that this is not the best analogy. The difference between them is enormous, and the main difference is the presence of a large amount of moisture in permafrost rocks. Permafrost rocks are extremely diverse; an extensive literature is devoted to their study and classification. But even if, as a result of practical work, an archaeologist has obtained an idea of a particular type of permafrost deposits, extrapolating this knowledge to the totality and variety of phenomena and situations hidden behind the concept of permafrost is illegal. In the practice of field archaeological research, we often encounter small "spots" in individual structures or mounds. Thus, the difficulties experienced by M. P. Gryaznov [1950] during excavations in Pazyryk and N. V. Polosmak [1994] during excavations of mounds on the Ukok plateau are well known. The features of permafrost under the burial mounds were studied during the excavations of the Berel group mounds in Kazakhstan (Gorbunov, Samashev, and Seversky, 2000). In this connection, it is concluded that its possible artificial (hu ... Read more
