Comments

Observer not sure of the trigger. There has been significant recent loading and wind, but at the time of the observation, the winds were light. Perhaps the first rays of sunshine... The large avalanche sympathetically triggered the size 1.5 and 1 to the left. The lower part of the large avalanche stepped down to the basal facets at the ground.
