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 in sheltered areas. 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. Average snowpack depths at treeline are near 70 cm and taper quickly as elevation decreases. Snow depths below tree line are generally below the threshold depth to produce avalanches.

Problems

Wind Slabs

An icon showing Wind Slabs
Recent wind has likely formed stiff pockets of wind slab in the lee of exposed features at upper elevations.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Increase your caution as you transition into wind affected terrain.

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

Elevations: Alpine, Treeline.
