The late glacial at the turn of the San Glaciation and the Ferdynandw Interglacial, studied in the sections Ławki and Ławki I in the open mine "Bełchatw", indicates wavy-like climatic changes. Four waves with milder climate and three waves of returning coolings were distinguished on the basis of changing lithology, traces of chemical and weathering processes, initial and well developed soils, plant remains and pollen analysis. Presence of remains of water plants corresponds with initial deposition phase of lake sediments. There are also loesses deposited in water. Several types of tundra vegetation were distinguished. Upper part of till of the San Glaciation was dated at about 596 ka and sediments of the described late glacial period at 563 ka.
