Large cornice triggered avalanche

Here's a large avalanche that was triggered by cornice cutting. Definitely ran bigger than expected. The average crown height was 45 cm but in places it was at least a metre.



There were some really big chunks of debris...


Here's a picture of the fracture line showing the rain crust from Sunday 17th Jan (purple arrow) and the failure layer (red arrow), which was a thin, soft layer of partly decomposed snow.
