Snowpack Summary

Snowpack has settled quite a bit since the storm exposing more early season hazards. Sun crusts exist on steeper south/southwest aspects. A field team in the Bruins Pass area noted moderate test results on the November 12 surface hoar layer, which is down between 50-110cm at higher elevations. Wind-pressed soft slab prevalent coming down 8812 Bowl.

Avalanche Summary

No new significant activity observed from previous 24 hours. Evidence in the Connaught drainage of an extensive cycle to size 3 during last week's storm. Old crown lines observed on N-facing slopes off of Cheops and Pk 8812 with debris traveling well into the fans.

Confidence

Due to the number and quality of field observations

Avalanche Problems

Persistent Slabs

Dig down to find and test weak layers before committing to a line.Avoid convexities or areas with a thin or variable snowpack.

Aspects: All aspects.

Elevations: Alpine, Treeline.
