Abstract : The aim of this study is to explain the dunes and deflation relief formed from sediments accumulated in an ice-dammed lake during the deglaciation in the Kaamasjoki-Kiellajoki river basin. At present the dunes are parabolic fossil dunes formed in periglacial conditions having been deposited by winds blowing from directions lying between WNW and NW. In the subarctic conditions prevailing today eolian activity resulting from the fact that effective wind directions are between W and SW is principally one of deflation. The results of the investigation into the evolution stages of eolian relief are presented in a chronological table in which are also given the periods of vegetation history, the types of vegetation, the climatic conditions and the estimated average July temperatures.
