Synonyms
Debris-mantled glaciers; Glaciers noirs
Definition
A glacier where part of the ablation zone has a continuous cover of supraglacial debris across its full width. Some authors apply a more rigorous definition of debris cover over at least 50% of the ablation zone.
Debris covered-glaciers probably exist in all the major mountain regions of the world, and are the dominant valley glacier type in high-relief orogenic belts, where high denudation rates of mountain faces supply copious quantities of rock debris by rockfall, rock avalanching, and mixed snow/ice/rock avalanching. They are especially well-developed in the Himalaya (Racoviteanu et al., 2008a), Karakoram (Owen and Derbyshire, 1993; Shroder et al., 2000), Caucasus (Stokes et al., 2007), Alaska, New Zealand (Kirkbride, 1993) and parts of the Andes (Racoviteanu et al., 2008b). Small covered glaciers are also widespread in some regions of cirque glaciation such as northern Iceland and the Sierra Nevada, California (Clark et...
