The maximum glacial extent and depression of equilibrium line altitudes (ELAs) in the Hiunchuli massif of West Nepal were reconstructed by air photograph interpretation. The present glaciers are characterized by either of the following two types: steep valley or valley sided type. On the other hand former glaciers were large plateau glaciers with many radial outlets. During the maximum glacial extent, the lowest ELA lay at an altitude of 4, 100m, about 1, 000m below the present ELA and the area of the maximum glacial extent was 200 km2, some 200 times as large as the present one.
