Quick report
- Collapsing
- isolated
Today's primary avalanche problems were wind slab and persistent slab. Wind slabs were found to be stubborn to unreactive in this zone today. Persistent slab avalanche activity was observed with two recent natural avalanches. Instability tests prove somewhat ineffective at measuring deeper, stubborn persistent weak layers.
We observed two recent natural avalanches. (See below for more information). Also, we observed some localized whumpfing on a ridgeline around 7800'.Weather

Both avalanches occurred naturally sometime within the past 48 hours. Both were on north-facing slopes between 7800-8100'. Both failed on persistent weak layers around 3 feet deep.
