Pollen analysis and AMS radiocarbon dating were conducted on the lateglacial sediments (175 cm in thickness) of a core obtained from the glacial Lake Ribno (2184 m) in the northwestern Rila Mountains. The vegetation dynamics at high-mid altitudes based on important changes in palynostratigraphy as a response to the lateglacial climate fluctuations for the time interval 16000-11600 cal.yrs BP is bound to an interstadial/stadial cycle, analogous with the Bolling/Allerod-Younger Dryas. The established local chronology demonstrates also good correlation with the isotopic signal from Greenland ice-cores. The reconstruction of the lateglacial vegetation shows common features with other sites from the Bulgarian mountains (Rila, Pirin, Western Rhodopes) and the glacial lakes in the southern Romanian Carpathians (Retezat Mountains).
