Avalanche Details
Snowboard caused avalanche. Wind slab broke at rider and carried him down slope. Seems to have failed at the interface of old new snow on fresh wind slab. Might have stepped down in areas.
Events of the day
We were playing around at the end of good hope all day. Nice temps and plenty of sun. No wind. We were there the day before and didn't encounter any winds. Our tracks from yesterday were still looking fresh and not covered by blowing snow so no real winds last night I'd assume.
Snowboarding down and felt the wind slab and the slab broke at the rider. Rider carried down and eventually able to gain footing and ride out. No bag deployed no injuries. Continued riding for the day and encountered no other incidents.
