Abstract. The paper presents the results of field studies conducted in the summer of 2023 in the Pechora River valley (Ust-Tsilma district of the Komi Republic). During fieldwork, we clarified details of geological and geomorphological structure of the river valley with the help of two cross section. In the Pechora river valley, we distinguish a floodplain and two terraces above the floodplain. Beneath the alluvial deposits of the low terrace and floodplain, we uncover deposits that we interpret as lacustrine-glacial deposits of the periglacial Komi Lake. Keywords: Pechora, Lake Komi, middle and late Pleistocene, drilling
