Primary Problem: Persistent Slab
Bottom Line: The primary concern is persistent slab avalanches breaking on weak layers near the bottom of the snowpack. Recent winds formed thick drifts which add weight to buried weak layers, and are a significant hazard on their own. Avoid slopes steeper than 30 degrees, especially slopes with recent drifts, and give a wide berth to the flatter runout zones below steep slopes.

Specimen Creek
Remotely Triggered Avalanche in Specimen Creek
Incident details include images
Specimen Creek
Coordinates: 45.0265, -111.0480
Caught: 0 ; Buried: 0

Many ridgelines had been scoured down to the grass from yesterday's winds. HS was around 100cm around 8k feet and significantly shallower at lower elevations. New snow totals from the past couple of days was around 20-30cm. We experienced a remarkable number of thunderous collapses throughout the day (I lost count), one of which triggered an avalanche into Specimen Creek while we were in the flats.

Dug a small test pit. Unprofessional observation ectp 10 on the persistent weak layer seen across the advisory area. On our way out near the cabin I cut a line close to a creek to see if I could trigger something.
