Most of these were failing on the January 30 surface hoar down 15-30 cm but at least two stepped down to the mid-January weak layer down 40-60 cm. The majority of the activity occurred between 1700 and 2100 m elevation. Many of the natural avalanches were on NE aspects and related to wind loading. A few were on SE-SW aspects which are expected to be related to solar triggering. The human-triggered avalanches were occurring on all aspects.

This MIN post shows what is likely a combination of wind loading and the persistent problem which is most likely around treeline elevations.
