Description :
Geoelectrical soundings were carried out in 29 different places in order to find permafrost and to measure its thickness. In most places above timber line a permafrost thickness of 10-50 m was recorded. Permafrost was found at sites with thin snow cover during winter. Here, deflation phenomena on the summits of fjells indicate the occurrence of permafrost. Vegetation type might be a good indicator of permafrost, too. It seems obvious that permafrost exists extensively on fjell summits of northern Finnland. - (L'A.).
