Abstract

Bedrock landslide contribution was investigated on the surface of one of eleven glaciers on a glaciated ridge in the Chugach-St Elias Range of southern Alaska, were the debris from 4 major landslides is easily distinguished from moraines and other supraglacial material. A series of aerial photos and satellite images from 1972 to the present constrain the interval of landslide deposition to the last 25 years. Because the landslides fell onto the ice surface in the ablation zone the deposits have not been incorporated into the ice; instead they are being carried down-valley as supraglacial deposits and have remained relatively intact
