ABSTRACT
The morphology of the Mazury Lake District (north-eastern Poland) dates from 24–19 ka (main
stadial of the youngest Vistulian glaciation). During this last glacial maximum (MIS 2) a belt with lacustrine
basins was formed when the ice sheet retreated at the end of the Pomeranian phase. The ice-sheet retreat is
morphologically also expressed by the occurrence of end moraines.
The study area is situated in the Skaliska Basin, in the northern part of the Lake District (near the Polish/
Russian border), at the periphery of zone with end moraines. Originally the basin was an ice-dammed depression
fi lled with melt water; the water fl owed out into the developing Pregoła valley when the ice retreated and
did no longer dam off the depression. The basin, which is surrounded by hill-shaped moraines, is fi lled now with
Late Glacial and Holocene glaciolacustrine sediments. The organic sediments of the basin record the history of
the Late Glacial and Holocene climatic changes in this region.
