Avalanche Summary
Several wet loose avalanches from steep south-facing slopes were skier triggered on Saturday.
Wind slabs are unlikely to be human-triggered. The most likely areas where wind slabs may linger are directly lee of high spots and ridge features.
Snowpack Summary
Roughly 20 cm of new snow is dry and settled on north-facing slopes and becomes moist on solar-facing slopes, covering a melt-freeze crust on all aspects and elevations.
A second crust formed in late March can also be found in the upper snowpack at variable depths depending on aspect and elevation.
A persistent weak layer of facets sits atop a second buried crust down 80 to 180 cm. This layer is unlikely to be human-triggered in areas where a thick crust above the weak layer is present.

Terrain and Travel Advice
- Wind slabs may be poorly bonded to the underlying crust.
- Carefully evaluate steep lines for wind slabs.
Problems
