Abstract
In an area in southwesternmost Värmland, western Sweden, ice‐marginal deposits have been mapped and studied. They can be correlated with the Norwegian Younger Dryas to Preboreal Ås, Ski and Aker ice‐marginal ridges, and with lines of ice recession earlier constructed in Dalsland. Together they give valuable information about the mode of deglaciation in southern Scandinavia. They indicate a pattern of deglaciation with intense upbreaking by calving of the ice eastwards from the Oslo Fjord and northwards in the Vänern basin. This process caused a downdraw of ice around the highland between those areas. Ice streams and, later, valley glaciers were formed in the large Årjäng‐Koppom and Glafsfjorden‐Byälven valleys. Between them a lobe‐shaped, stagnant ice cap was isolated from further supply from the main ice sheet in the north. This ice cap, here called the Dal lobe, wasted down with a complicated pattern from the west, south and east.
