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 surfaces 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.

- Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
- Be carefull around freshly wind loaded features.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
Problems
Persistent Slabs
A crust from early February has produced avalanches in the region. This layer is problematic where facets overlie it.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Wind Slabs
Recent new snow has formed wind slab at higher elevations.
At lower elevations this new snow could run as a wet loose avalanche as the freezing level rises.
Aspects: North, North East, East, West, North West.
Elevations: Alpine, Treeline.
