Avalanche Problems

Deep Persistent Slabs

Within the past week there have been occasional reports of skier remote and explosive triggered slabs on the Oct 26 crust & facet layer. Avoid steep terrain where a stiffer, more cohesive slab exists over the weaker snow at the base of the snowpack.

Whumpfing is direct evidence of a buried instability.If you are increasing your exposure to avalanche terrain, do it gradually as you gather information.

Aspects: North, North East, East, South East.
