More detailed information about the snowpack: 

Limited signs of instability in the Granite zone today. The main instability was minor skier triggered loose dry sluffs on steep terrain. Aside from isolated shooting cracks in obvious wind slabs near ridgelines, there were no signs of slab instability. No results on the persistant weak layer in this area today.
