The paper presents the results of pollen analysis and radiocarbon dating of a peaty mud sample from a gravel-sand outlier of the Vistulian alluvial fan of the Dunajec River. The study showed the occurrence of open birch-pine forests with sporadic larch and stone pine at the time of mud deposition. The vegetation, of park tundra type, was characterised by the development of shrubby and sedge-grass communities. The radiocarbon dating of 39 100 ± 3000 BP indicates that deposition occurred in the Middle Plenivistulian (Hengelo interstadial or older, colder climatic stadial). A comparison of the palynological analysis and radiocarbon dating with data from other sites suggests that both the alluvia of the north-western part of the Dunajec River fan and the alluvia of its southern part were formed during the Middle Plenivistulian.
