Abstract

To obtain knowledge on rockwall retreat rates at sites with rock glaciers, an inventory of about 400 individual rock glacier sites in West Greenland was carried out by means of field studies, and using aerial photographs and topographic maps. Especially, the result shows that, headwalls above glacier-derived rock glaciers are exposed to high weathering rates, and thereby presumably delimit critical ranges regarding altitude for headwall retreat rates. The relation of such a critical altitudinal range to other regional concepts, such as glaciation level (GL) and glacier equilibrium line, is discussed
