Studies of the glaciers located on the Verkhneangarsky mountain range
Glaciers of the Verkhneangarsky mountain range are discovered in 2017-2018 and require detailed investigation and cataloging. This group of glaciers includes glaciers of the corrie and morphological types, and, according to the sizes, they should be qualified as small forms of glaciation. Four glaci...

The temperature of ice in the glaciers of this region was measured during the investigations.
