It is likely that the collapse this group felt was the trigger for both the north facing avalanche(s) and the wide southerly facing avalanche.

Avalanche Details

About 3300', middle of three skiers on unptrack felt wumph with step. Audible wumph preceded break, slide was quickly out of view on the north side of Cornbiscuit. Dust billowing down at the creek toward Magnum let us know the slide ran to valley floor. No people known or believed to be in the path.

Parties below and to the south let us know that another slide occurred at the same time on south aspect, possible propagation around the ridge. Waited for parties below to clear out. On decent, long crack (~1cm wide) ran downhill from south to north around the ridge. From below, crown (north aspect) spanned two gullies.
