Things are getting tricky with our PWL as red flags decrease, and we are seeing less obvious signs of avalanche hazard. In many places on the north half of the compass, sugary, weak, faceted snow is preserved beneath a 2-4’ slab of cohesive snow. As time has worn on, the likelihood of triggering these avalanches has gone down but the consequences, if triggered, remain the same.
While stability tests and the lack of avalanche activity suggest strengthening of this weak layer, there is still a likely chance of triggering a large avalanche remotely, or from a distance that could keep you from coming home at the end of the day.
