Primary Problem: Persistent Slab
Bottom Line: Stability is improving slowly in the Southern Madison and Southern Gallatin Ranges and the mountains around West Yellowstone. Persistent weak layers buried 1-3 feet deep make human-triggered persistent slab avalanches likely on steep slopes. Without fresh snow, obvious signs of instability, such as collapsing and shooting cracks, will decrease. For now, seek out great powder turns and ride in low-angle terrain, avoiding slopes steeper than 30 degrees.

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.
