    A crust from early February has produced avalanches in the region. This layer is problematic where facets overlie it.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported in the past couple days.

Snowpack Summary

Around 10 cm of new snow has buried a variety of layers including surface hoar in sheltered terrain, a crust on south and west facing slopes as well as old wind slab on exposed terrain. A new crust may be found on sun exposed terrain and all aspects below treeline.

Another layer of surface hoar is down around 20 cm in sheltered areas.

The widespread crust buried in early February is down 30 to 50 cm and has sugary facets on top.
