The current snowpack demands a thoughtful approach to avalanche terrain. Avoid steep terrain with shallow, variable snow depths where triggering deep weak layers is more likely.

Snowpack Summary
Roughly 10 cm of low-density snow since the weekend overlies a generally well-settled upper snowpack. The mid and lower snowpack consists of loose facets, with a significant weak layer of large facets and a crust down 80 to 120 cm from the surface. The snow below this weak layer is generally weak and unconsolidated.
Treeline snow depths are roughly 140 to 160 cm.
Weather Summary

Terrain and Travel Advice
- Uncertainty is best managed through conservative terrain choices at this time.
- In areas where deep persistent slabs may exist, avoid shallow or variable depth snowpacks and unsupported terrain features.
- Don't let the desire for deep powder pull you into high consequence terrain.
Problems
Deep Persistent Slabs
Human triggering of deep persistent weak layers remains possible, especially in shallow areas with variable snow depths. Consequences could be severe if triggered.
