Land/sea level changes in southern Finland during the formation of the Salpausselkä endmoraines

| Summary: | The altitudes of delta plains of the Salpausselkä endmoraines and of eskers, as well as some determinations of the highest beach level, were used in the study of land/sea level changes. An area south of Hämeenlinna in southern Finland was studied in more detail and compared with Salpausselkä I at Lahti and Utti. It was found that there is a zone in the Salpausselkä belt, partly including Salpausselkä I, and reaching to a line inside Salpausselkä II, in which the outwash features were formed during a high position of the water level, when the Baltic Ice Lake was dammed and its level higher than the sea level. The transgression began 8 600–8 700 B.C. and ended with the drainage of the Baltic Ice Lake at Billingen in Central Sweden in 8 213 B.C., when the water level dropped to the Yoldia level, Y I. Before the transgression the deltas, which mostly belong to Salpausselkä I, were formed at a low position of sea level, the g level. A curve of the land/sea level changes covering the last 11 000 years was constructed on the basis of the results from the present study and earlier investigations in the same area.
