GREY AND MAUD

 

Event description

 

The rock avalanche, inspected on 20 September 1992, removed a long section of ridge line. The ridge probably did not fail over the full height of the slope, and a smaller volume, perhaps 5 Mio m3, failed. It did , however, remobilize most of the earlier deposit, and thus had the greater deposit volume. The avalanche blanketed the Maud Glacier with debris and entered a proglacial lake.
