of the glaciers. An up to 8 m thick winter snow layer
was measured in the accumulation area (∼4 m w.e.). Ice melt
of up 10 m w.e. was measured in the lowest part of the ab-
lation zone in summer, and 2 m w.e. was melted during
win-
ter. Taking into account ∼2 m of annual rainfall, the runoff
from this part of the glacier was estimated as ∼14 m w.e. per
year; a surprisingly high value (Ahlmann, 1939
