Comments
Remotely triggered from the ridgeline. Party had felt numerous collapses and observed shooting cracks while climbing the ridgeline. Weak interface of 1st week of January faceted snow just beneath the 9tjh/10th prefrontal southwesterly wind slab (3")...now buried under 16-20" storm snow. Key - in my opinion - that the suspect areas saw some wind drifting prior to the storm.
