The article concerns a problem of occurence of windthrow structures on archaeological sites. This specific objects, caused by falling trees, are sometimes misinterpreted as features of anthropogenic character. An attempt of reconstruction of generating the micro-depressions and their filling was proposed. It is, in general, convergent to the one presented by soil scientists (e.g. R. Langohr). However, in author's opinion, such objects should not lose their importance as archaeological sources, since they may reflect history of the sites. Greater amount of simultaneous windthrow structures might also be an indicator of the climate destabilisation in certain periods.
