Abstract
An ongoing geomorphological research project on nivation and local glaciation is testing the following working ./ hypothesis. After the main Weichselian deglaciation in south Sweden, periods of cold tundra conditions returned, e.g. in the Younger Dryas period. Fossil ice-wedge casts and rocks with wind-polis- ^// hed facets and flute marks indicate permafrost climate and _ strong winds with snow-drifting from easterly and westerly direc- tions. Large masses of drifting snow were trapped in the canyon valleys of Soderasen and other horst ridges, where nivation / hollows and small glacial cirques were slightly rejuvenated. Ni- / veo-eolian sand was deposited in some hollows and also incorpo- // rated in some moraine-like deposits. The bedrock hollows and cirques were mainly excavated during the much longer tundra 64// periods before the advances of the Quaternary main ice sheets over Scania. But the hollows survived the erosional impact of the ice sheets. The work to test the hypothesis is making progress, by analysis/// of the Late-Glacial forms and material in south Sweden, by comparisons with landforms, material and processes in the actual , // mountain tundra of Abisko in the north, and by comparisons - /
