Avalanche Summary

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

Snowpack Summary

There is up to 10 cm of moist new snow from the past few days at upper elevations. Recent reports suggest there is an average of 60-120 cm of snow in the alpine. This decreases dramatically with elevation where the primary hazards are rocks, stumps, and open creeks. We currently have very limited snowpack observations, so it is critical to supplement this information with your own observations.10-15 cm of recent snow is sitting on a crust that was formed during a temperature inversion that happened last week. Surface hoar (weak, feathery crystals) that formed during last week's dry period were likely melted by warm temperatures, but may have been preserved on sheltered, north facing slopes at treeline elevations. Expect to find an early season crust near the bottom of the snowpack in many areas.

Problems

Wind Slabs

An icon showing Wind Slabs
The slopes that have the most snow to ride, may also be in areas most likely to trigger wind slabs.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Stay alert to changing conditions with elevation.

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

Elevations: Alpine.
