Natural soft slab avalanche occured in the last 24hrs in the steep sheltered trees above the log cabin mine site. Appears to have failed within the new storm snow and stepped down to the facet layer just above the ground. See attached crown profile, maps and photos.
On the way up to do a crown profile, many long (50') shooting cracks on small rollovers (see shooting crack photo).
