Abstract. A complex of field and remote methods made it possible to determine the growth rates of thermocirques (retrogressive thaw slumps) on the territory of the key site Vaskiny Dachi (Central Yamal). The distribution of growth rates along the perimeter of the retreating edge is uneven, the average growth rates of three thermocirques in 2017-2021 vary within 5.2–12.5 m/year. The maximum observed growth rates were 52.4 m/year. It has been noted that the growth dynamics of thermocirques is determined by the relief of the slope into which the thermocirques are embedded, as well as by climatic fluctuations.
