Comments
We witnessed this avalanche today while out with an AST group on Summit Creek Knoll from about 5km away. Can't confirm trigger but Natural is unlikely. I suspect this was remotely triggered by recreational groups in the area or from a cornice failure. Though we did not have the conditions for a cornice failure and today. We did see groups coming out of the valley at the end of the day but we were not in position to intercept them and find out more information. This terrain feature is very similar in aspect and elevation to another feature which produced a large remotely triggered avalanche on Friday.
