15">Researches in the last several years revealed that 16 small firn/ice features of a permanent character (small glaciers) still survive in three mountain ranges on the Balkan Peninsula: Prokletije (Albania), Durmitor (Montenegro) and Pirin (Bulgaria). All glaciers are located in north and northeast facing strongly shaded cirques of carbonate bedrock (limestone, marble) at altitudes from 1910 to 2620 m a. s. l., and usually have areas from less than 1 ha to 5–6 ha.
For the last 10 years all small glaciers of the Balkans have shown considerable inter-annual variations of their size. Observed fluctuations have been quite synchronous in the three studied mountains. In a long-term sense, no trend has been registered towards shrinkage or increase. Analyses of climatic data have shown a considerable relation between glacier size and summer temperature, and winter precipitation is a second factor.
