AbstractIn the area around Abisko and Björkliden some new observations of different types of permafrost mounds have been made. The features include forms which resemble palsas, pingos and frost blisters. The observations are made in an area where several“fossil pingos”have been reported. This paper gives a preliminary description of the observed features, their possible genetic background, terminology and their possible relations to other permafrost features, both recent and fossil, of the region.
