Jan 30, 2022 (FCsf)Comments:
Remotely triggered from 20-30 feet away. Cracks visibly connect trigger point and crown. Crown ranged from 35cm to over 100cm above an unsupported convexity. Uncertain of exact weak layer. Reported to fail on facets in uniquely shallow snowpack. Possibly repeat avalanche producer. See associated observation for crown profile. The exact elevation may have been between 6,000-6,700ft.
