The glacier is heavily crevassed in its lower half, receiving ice influx also from Balkan Snowfield and from the part of the island’s ice cap that is located west of Hemus Peak and Gurev Gap and south of Saedinenie Snowfield, and is draining southwards. It exhibits pyroclastic phenomena typical of the region’s glaciology and resulting from volcanic activities at Deception Island not 40 km away.
The glacier was mapped by the Spanish Servicio Geográfico del Ejército in 1991, the lower portion in greater detail. Bulgarian remapping of Perunika Glacier’s terminus from a survey made during the summer of 1995-96; mapping in 2005 and 2009 from the Bulgarian topographic survey Tangra 2004/05.
Perunika is the name of a village in the Rhodope Mountains in southern Bulgaria. A derivation of Perun, the name of ancient Slavic God.[1]
