If you're out in the hills, don't forget to post to the MIN. Every bit of information helps!

Snowpack Summary

High freezing levels will continue into Saturday. The alpine and open tree line terrain is wind affected. Large facets and depth hoar comprise most of the snowpack. The snowpack varies from 50-85cm in depth and is unsupportive.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.

Avalanche Problems

Deep Persistent Slabs

The bottom of the snow pack is inherently weak with well developed Facets and Depth Hoar. Avalanches initiating in the upper snowpack are likely to step down to this layer and gain significant mass.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 3

Wind Slabs

Aspects: North, North East, East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
