Abstract The article is a somewhat developed report of a lecture given at the Würm Symposium at Kristineberg, October 13, 1973. It gives an account of what is known about the last glacial in the central area of glaciation. Two glacials (Weichsel I and II + III) can be identified in this area. In the southern and western parts of Scandinavia three glacials (Weichsel I, II and III) can be traced. The Weichsel I ice had a southeasterly orientation controlled by the mountain range. The Weichsel II–III ice had a northerly-easterly orientation, independent of the range. The two interjacent interstadials (the Jämtland and Göta Älv Interstadials) have been dated at >40 000 and about 25–35 000 B.P., respectively, in Sweden. In the Jämtland Interstadial almost the whole of Scandinavia was deglaciated, in the Göta Älv Interstadial probably only the West Coast and the southernmost part. These interstadials are correlated with the Brörup Interstadial and mid-Weichsel complex on the Continent. Some aspects of the causes of glaciation and the refugie problem are also given.
