The crown broke about 10 feet down from where the snowboarder made a stop at the top of the ridge. We noticed a hairline crack a couple feet above where he stopped (essentially he was in between the crack and the crown). The snow on the surface was fairly soft and seemed wind loaded. The snow on the track up was a thin wind crust. Rough slope angle measurement from the bottom was 30°-32°.
Slab that slid had a very noticeable weak layer, which more than likely was just under the recent snowfall this week. Estimated 50 foot wide (at the narrowest), 3 foot deep, and ran to all the way to the bottom.
