Abstract
Glaciers in the little‐known region of the Tenianyy Range, Chukotka, are described on the basis of field work carried out in August 1988. The equilibrium line on these glaciers lies at about 500 m; accumulation averages about 190 g/cm2. The glaciers occupy steep cirque slopes and are heavily covered with debris. No crevasses have been detected. Due to an unusual distribution of snow on the surfaces of the glaciers, whereby it tends to accumulate on the lower parts, the ice in the upper portions of these glaciers is free of snow; this results in thinning and gradual disappearance of the ice in the upper parts. All the glaciers are in a stage of degradation. Snow patches are widespread in the region. It is concluded that present conditions are inimical to glacier formation and survival in the Tenianyy Range.Keywords
