GREY AND MAUD

 

Event description

 

The rock avalanche, inspected on 5 May 1992, removed a 250 m length of ridge immediately to the northeast of Mount Fletscher. A large butress supporting a small glacier on the face also collapsed, indicating failure over the full height of the dome. The volume of this avalanche was 5 - 10 Mio m3. The avalanche blanketed the Maud Glacier with debris and entered a proglacial lake.
