More detailed information about the snowpack: 

We avoided avalanche terrain today on our tour. We did come across several obvious wind slabs which were able to produce small and medium shooting cracks under the weight of a skier. The largest crack ran approx 10ft. No other signs of instability today other than surface weaknesses.
