Avalanche Problems
Deep Persistent Slabs
The weak base of depth hoar and facets is now less sensitive to human triggering. We have now entered a period of "low likelihood - high consequence". Shallow and faceted areas are likely trigger points.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 2 - 4
