The widespread occurrence of dolomite results in the typical appearance of much of the Ammergau Alps: great streams of dolomite scree, the so-called Gries, which fills entire valleys (such as the Graswangtal). The most intensive examples are in the area of the Kreuzspitze and on the north flanks of the southern main chain of mountains. The Friedergries and the Lindergries are particularly notable areas of deposition in the valleys. One unusual topographic feature is the Kessel, a large doline funnel in the area of the Hasentalkopf, that was deepened as a result of the loosening of rock.
