This frequent runner \ occurred during a severe wind loading event with 13" of new snow and sustained 35-45 mph winds. This particular slide path is very susceptible to heavy loading from SW-NW winds. We had been tracking a spotty layer of facets that was covered up on Valentines Day. It is unknown if this avalanche failed on that layer or on the Feb 22 Interface.
On the day this avalanche was observed we dug a snowpit on NE aspect at a lower elevation and noted the following weak layers/interfaces.
