No need to do a stability test. This slope collapsed like many others like it.

Deep fresh snow with little or no base in most places.. Northerly facing terrain above about 8000' holds shallow old snow (Oct. and Nov.) in some areas plagued by facets above and below a rime crust.

Triggered a large collapse on this slope. Many large cracks, some as big as 6 inches wide. Collapse covered an area 250-300 feet wide but wasn't steep enough to slide

There is a lot of variability from winds about 5 days ago. Under the new snow from the Dec 14 storm, the dense layers of wind blown snow are think in some places, and thin or non-existant in other areas.
