Recent Avalanches, Heavy Snowfall, Wind Loading, Poor Snowpack Structure
Elevation

We dug a pit near the large avalanche on Bonner's Ridge from Dec 29th but kept a safe distance and a slope of 25 degrees. Compression tests were showing new snow breaking at 6-7 taps and PWL breaking at 11 to 16 taps. Pictures below is steep rollover that is facing North 35+ degrees. This was a natural release probably on Dec 31. Heavy winding loading from SW winds.

<p>New slab on top of PWL is my largest concern. </p>
