Toured Microdot and Rae Wallace. Noted a human-triggered cornice fall down the typical uptrack which could have injured or killed a person. Since then, cornices have grown bigger. No surface hoar noted at mid elevations where cloud layer existed. Dry loose snow and soft slabs on steeper aspects with minimal propagation.

BEFORE the winds started ripping on 1/15, we toured Rae Wallace on 1/14 and there had been significant, probably skier-triggered, cornice fall down the boot-pack shoot from the top to the apron. There were refrigerator-sized blocks which could certainly kill a person.
