Abstract: The results of geological, geoelectrical and radiometric investigations of small depressions in the natural reserve “Meteoryt Morasko” are discussed. The interpretation of results suggests the impact origin of six hollows existing on the north-east slope of Morasko Hill (Moraska G5ora near Poznań). The area of the reserve is unique in its combination of the occurrence of meteorites and the morphological effects of their fall. © 2001 Published by Elsevier Science Ltd.
