Two members of the Society, Dr. S. E. Hollingworth and Mr. W. Vaughan Lewis, joined Dr. K. M. Strøm’s expedition to the Rondane Mountains of Central Norway in June 1946. The principal subjects of study were geomorphological problems associated with the glaciation of the area and the mode of disappearance of the last Pleistocene ice-sheets. The detailed work of Dr. Strøm and his collaborator, Hr. Tore Sund, have amply confirmed the earlier view of Dr. Carl M. Mannerfelt, based on studies in Sweden and Norway, that the ice in the mountain areas became “climatically dead” at an early stage in the waning of the Scandinavian ice-sheet. The snow line was well above the level of the surface of the ice when the latter stood at 1600 metres. A wonderfully complete series of marginal channels with kettle-holed ablation moraine, outwash and fluvioglacial deposits characterize later stages in the decay of the dead ice.
