   Pollen analysis was used to study a sediment of Last Glacial age, burried beneath younger deposits. Radiocarbon dating indicates that the profile reflects events at least for the period 16 000 to more than 52 000 14C BP. Five vegetational-developmental phases are delimited: SF1 - larch stands under a very cold continental climate (analogy of forest tundra at the polar tree limit of todays Siberia); SF2 - birch - larch stands suggesting a cool continental climate (transition of forest tundra to the northern Siberian taiga); SF3 - pine - spruce stands with birch, larch and alder (analogy of the northern zone of middle Siberian taiga - climate with a higher humidity); SF4 - spruce stands with a greater contribution of alder and the continued presence of other tree species (analogy of natural forests of Carpathian basins during the Holocene climatic optimum); SF5 - pine stands with larch. Spruce is retreating (decrease in temperature and humidity).
   The unique feature of the studied profile consist in its geographic position. It represents the first source of palaeobotanical data for the period of the Last Glacial in Slovakia. Unfortunately, exact age of individual profile layers is impossible to determine so far. Existing radiocarbon data were obtained from wood and cones collected at already disturbed profile. Small pollen-analytical samples, collected in the field during the salvage operation, were lacking material appropriate for the purpose of dating. Due to difficult conditions during the sampling of the profile, is was also impossible to perform detailed stratigraphic investigation directly in the field, but, according to overall geological context, the peat had accumulated in the fossil doline during the Last Glacial period
