Date of Observation: 01/31/2021
Zone: Northwest Mountains
Location: Kebler Pass BTL
Aspect: North East
Avalanches: Skier triggered R4 D1.5. Released near the top of the slope in the middle of the convexity and propagated across most of the face.
Weather: Sunny and clear skies. Around 10am.
Snowpack: My best guess is it was storm slab that failed on the mid January facet layer. The debris was still fairly soft but deep enough to catch and bury a skier.
