Avalanche Summary

No new avalanches have been reported in the region. However, we currently have very limited observations. If you have been out, please submit any observations to the Mountain Information Network MIN.

Snowpack Summary

Approximately 5-10 cm of new snow possibly sits on top of a widespread layer of weak, feathery surface hoar crystals. The new snow has been redistributed by recent southerly winds. A mixed layer melt-freeze crusts and sugary facets buried late October can be found at the base of the snowpack at treeline and in the alpine. Snowpack depths taper quickly as elevation decreases. Snow depths below tree line are generally below the threshold depth to produce avalanches.

Problems

Wind Slabs

Recent wind has likely formed thin wind slabs in the lee of exposed features at high elevations.

Increase your caution as you transition into wind affected terrain.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

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

Elevations: Alpine.
