after the locality became ice free, the climate
became very cold with many years of perma-
frost in the lowland. Such a cold climate has
hardly occurred in Iceland for the last 10.000
years. Thus, Búdi stage, i. e. Younger Dryas
time, is the youngest possibility for the
formation of the ice wedges and consequently
Saurbær interstadial (Allerod) time for the
deglaciation of the Skagafjördur valley.
ACKNOWLEDGEMENTS
The fieldwork was carried out in the summers of
1974 and 1975 and was financed by the National
Energy Authonly (Orkustofnun), Reykjavík, the
Unwersity of Bergen and Nordisk kulturkommision.
The fieldwork was used as the basis for a Cand. Real.
thesis (Víkingsson 1976j. Supervisors during
fieldwork and preparation of the thesis were Dr.
Bjorn G. Andersen (Univ. of Bergen) and Dr.
Thorleifur Einarsson (Univ. of Iceland).
