Avalanche Summary

No new avalanches were reported on Tuesday. However, observations in this region are currently very limited.

Please consider sharing your observations to the MIN.

On Monday, a rider remotely triggered a size 2 wind slab on a northerly aspect in the alpine. The bed surface was a crust. See MIN

Snowpack Summary

At upper elevations, 5 to 10 cm of recent snow has been redistributed by southerly wind.

A significant crust is down 20 to 100 cm.

Snowpack depth ranges from 50 to 150 cm at treeline and above.

Snow depth tapers rapidly with elevation.

Rocks, stumps, logs, and open creeks pose a significant hazard in many areas.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Use small, low consequence slopes to test the bond of the new snow.
  • If it's deep enough to ride, it's deep enough to slide (avalanche).
  • Be cautious of buried obstacles, especially below treeline.
