Experienced near-continuous cracking and collapsing from near the river to 9700 ft. Gusty wind with lots of wind-transported snow and periodic heavy snowfall.The plan for the day was to ski an open 30-34 deg bowl but we bailed on that plan after seeing many blaring signs of severe instability and retreated through the thick woods we ascended. Visibility was too poor to tell positively if there was natural activity in the more open terrain.
