Calving bays, striae and moraines at Gysinge-Hedesunda, central Sweden

Authors(s) and Affiliation(s)



Reconstructions of the retreating margin of the inland ice during the last deglaciation have shown that calving bays or estuaries were frequently formed in subaquatic areas. Such more or less deep bays in the ice margin are indicated by the pattern of striae, moraines and eskers. They have also been traced or verified by clay varve data. Varve measurements have shown that deep estuaries were formed at the courses of glaciofluvial drainage, now represented by eskers, and that the interjacent areas were covered by prominent ice lobes. The moraines, which are long winding till ridges, oriented almost parallel to eskers, are located in areas covered by these lobated sections of the inland ice. It is suggested that the ridges are correlated to basal crevasses in the lobated parts of the ice margin.
