Pollen analyses and 14C-datings were carried out on two late glacial profiles from Ruegen Island, Mecklenburg-Vorpommern at the southwestern Baltic coast. The palaeoclimatic and palaeoecologic interpretations were supported by carpological investigations. The organogenic deposits of the 'Hoelle' outcrop near Dwasieden Park were chosen because of their unique stratigraphic position, which according to PANZIG (1989), lay under a m3m-Glacial Till of the Mecklenburg Advance (W3). The results indicated that the initial phase of the late glacial sedimentation in a relatively small and asymmetrical lake basin (in comparison with the larger Nieder- and Credner lake to the southwest), probably had its origin in the older Alleroed (II a) after FIRBAS (1949). The basal clastic sediments were rapidly followed by peat deposits and later, due to a rising water table, by muds rich in organic matter. The area was covered with sparse Betula-(Pinus) forests having heliophilous late-glacial elements typical of the surrounding areas during the younger Alleroed (II b). With the climatic change to colder and drier conditions at the beginning of the Younger Dryas (III), the vegetation decreased and enhanced erosional processes led to the fill up of the depression with fine clastic sediments. The intense relief differences of the surroundings coupled with high water saturation in the sediments led to solifluction in the m3m-Glacial Till and its placement discordantly over the organogenic sequence.
