Two snowmachiners were caught in the avalanche they triggered. It released at a faceted layer beneath a hard slab (ranging from 30-70cm in thickness) HS-AMuR3-D3-O. The crown fractured along an East through North East slope above a gully terrain trap. The crown face was 30-70cm in depth, 200ft in width, and 800ft in vertical run. All numbers are estimates as direct access to the crown was not possible due to avalanche danger.
