Comments
Wind slab that probably stepped down to facets. See marked slide in right part of photo.
Forecaster note: Avalanche fits the pattern of several others noted during the cycle - new and wind drifted snow providing enough of a load to cause a failure down to persistent weak layer of facets/depth hoar from October snow.
