Contemporary state of glaciers in Chukotka and Kolyma highlands
The purpose of this work is to assess the main parameters of the Chukotka and Kolyma glaciers (small forms of glaciation, SFG): their size and volume, and changes therein over time. The point as to whether these SFG can be considered glaciers or are in transition into, for example, rock glaciers is...
