Kolka Glacier

Kolka Glacier is a cirque, valley and hanging glacier in North Ossetia-Alania, Russia, near Mount Kazbek in the Caucasus Mountains, covering about 2.47 square kilometers and extending roughly 3,130 meters between an elevation of about 3,000 and 3,450 meters above sea level. The glacier is known for periodic surges, fed year round by avalanches and ice collapses and prone to accumulating meltwater beneath its ice; its most recent and most powerful surge, on 20 September 2002, killed about 140 people. The glacier's terminus rests on moraine, and it is currently classified as growing rather than retreating.
