    Cornices are weak and may break further back on ridgelines than expected. These large loads can trigger buried weak layers on the slope below.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Make observations and continually assess conditions as you travel.

Confidence

Moderate

Avalanche Summary

Over the weekend, small wet loose avalanches were reported to size 1.

And on Friday, skiers remotely triggered a slab on a northeasterly lee ridge feature at treeline near Mt. Fisher.

Snowpack Summary

The snow surface is likely a crust at higher elevations, transitioning to moist snow as you move below 2000 m. High alpine north facing slopes may still hold dry snow above a thick crust from late March.

The snowpack is quickly disappearing below treeline.
