Ice avalanches |

| Description |
In the late afternoon a part of the front of the Frebouzie glacier avalanched. The ice avalanche descended 400 m of the steep rock step and covered a 100.000 m2 area of the apical part of the polygenic fan, the inclination of which is about 20°. The lower front of the deposit reached an altitude of 1855 m asl. A few ice boulders reached a lower altitude, coming to rest 100-150 m ahead the front of the main mass. Some huge boulders exceeded 20 m3 of volume. The volume of the avalanche was at least 100.000 m3. The ice deposit quickly melted in two weeks. |
