Characteristics of Glaciers in the Khumbu Region and their Recent Variations

Abstract

The glaciers in the Mt. Sagarmatha (Everest) region can be classified into two types, namely, "debris-covered type glacier" and debris-free "clean type glacier". The sizes of the former type are large, the latter small. The difference of elevation between the present terminus of the clean type glaciers and the most recent terminal moraine in the Gyajo area was 300-400 m. The glaciers in the Mt. Sagarmatha (Everest) covered by debris, and debris-free glacier (Mori-region can be classified into two types; debris-bayashi, 1974).
