The Khumbu Glacier, Khumbu region, east Nepal, is a typical debris-covered glacier on the south side of the Great Himalayas.<BR>The occurrences, distributions and grain size measurements of the supraglacial debris of the Khumbu Glacier show the following results.<BR>1) The longitudinal zonal distributions with different kinds of debris can be traced even down to the glacier terminus. 2) The traverse zonal distributions of the schistose debris are found. 3) The schistose debris are mainly composed of pebbles and cobbles, while the granitic debris contained many boulders coarser than -8φ (256 mm in diameter). 4) The measurements of debris grain sizes shows that there are high contents of coarser debris found from area IV near the ice fall down to area II near the present active terminus, while there are low contents of coarser debris found in the area I of the stagnant ice body. 5) The supraglacial round debris are found in the area II near the present active terminus and in the area I of the stagnant ice body. 6) Layered englacial debris are also found at the ice cliff in the down-stream part of the Khumbu Glacier.
