Abstract

Maximum limit of the Vistulian Glaciation in the southwestern Mazury Lakeland was determined on the basis of detailed geomorphologic and geologic fieldworks. The main obstacle for the advancing ice sheet were the end moraines, formed during the Mława Stadial of the Wartanian Glaciation. In spite of lacking tills and morainal features of the last glaciation, a maximum limit of the ice sheet of the Vistulian Glaciation was determined in this area, basing on southern limit of glacial channels, lakes and kettle holes. On the Nidzica Plateau which was a forefield of the ice sheet during the Vistulian Glaciation, there are depressions with biogenic sediments of the Eemian Interglacial, surrounded by patches of older till and its residual lag concentrates.
