The problematics of landslide chronology stands for an important field of geomorphological investigations in the area of Outer Western Carpathians; in particular, in connection with the consequences of research of the impact of climatic change on morphogenetic processes. A large slope deformation has been selected in the area of Silesian Beskydy Mts. near the town of Jablunkov. Three samples of bottom material of intercoluvial peat bog on the right slope of Kotelnice Brook valley have been dated by radiocarbon method (Gd: Radiocarbon Laboratory Silesian Technical University, Gliwice, Poland; 14C: 4,2-4,25 m = 10 235+-290 B.P. (Gd-16156); 3,66-3,7 m = 9854+- 470 B.P. (Gd-18168); 2,65-2,70= 11 813+-383 B.P.(Gd-18164) and pollen analyses (Late Glacial to Holocene). The minimum landslide age has been determined for the period of Younger Dryas to Preboreal. The landslide belongs to the landslide period S] (e.g. MARGIELEWSKI 1998).
