We triggered a cornice first thing in the morning. We are used to this area, we were going to drop our snowboard at the top of the zone. The first sled that parked triggered the whole bowl from the cornice. Depth was maybe 1 foot.

We did not take actual numbers and it was enough for us to call it a sled day only, we know this face very well and would not have risk it. Throughout the day we seen few cornices let go into a sluff too.
