Avalanche Summary
Over the weekend, small wet loose avalanches were reported to size 1.
On Friday, skiers remotely triggered a slab on a northeasterly lee ridge feature at treeline near Mt. Fisher.
Snowpack Summary
5 to 10 cm of new snow likely sits on a crust at higher elevations, transitioning to moist snow 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.

Terrain and Travel Advice
- This is a good time for exploring terrain.
- 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.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
