2.  Obruchev Glacier is located in the Polar Urals. It is a
typical temperate cirque glacier and it covers an area
of 0.3 km2. The glacier is 0.9 km long. The altitude is
ranging from 397 m (in 1981) to 650 m a.s.l. The
mean ELA is located at 520 m a.s.l. The glacier has a
maximum depth of 120 m. The velocity of the ice
movement is up to 6 m per year. Between 1960 and
1981 Institute of Geography of USSR Academy of
Sciences (now the Institute of Geography of the
Russian Academy of Sciences) carried out complex
glaciological investigations every year semi-
stationary (summer). Most of them were early
measurements of winter and net (at the end of the
ablation season) mass balance using poles and snow
measuring probes.
