Comments

Widespread natural aciivity: all wet. Multiple Wet Loose Avalanches on all aspects. Slope angles 35 degrees and greater. Most appeared to initiate Wet Loose and many entrained into Wet Slabs. Debris piles at a meter or more in many places. Slope cuts easily triggering Wet Slabs. Depths of slides 10 cm to 25 cm. All slides appearing to slide on the old snow/new snow interface (melt/freeze crust). Slides moving slowing, but entraining substantial amounts of debris upon descent.

Rain/snow line appeared to be at 9700 feet in the morning hours, and rise to above 10,000 in the afternoon.
