Date of Observation: 02/06/2021
Zone: Northwest Mountains
Location: Sunny Shoulder on Irwin Tenure
Avalanches: The slope failed when I was more than half way down. I never felt or heard a collapse. The avalanche overtook me at the bottom of the slope. I was buried around a tree with a good air pocket. Partner had me dug out in 6 minutes.
Snowpack: Multiple m/f crust facet layers with our latest two storms on top. The slope had seen four 2-pound explosives as well as an 18-pound air blast the day before with no results.
