Avalanche Summary
A few wet loose avalanches were reported on Tuesday from slopes facing the sun.
Several small (size 1-1.5) storm slabs were reported on Monday. They were more reactive in places where the wind had loaded.
Snowpack Summary
10 to 20 cm of recent storm snow sits on a layer of small surface hoar which may lurk in sheltered areas. In some places, the new snow and surface hoar sits on a thin sun crust.
A thick rain crust from early February is now buried 30 to 40 cm deep and seems well-bonded at lower elevations.
Crusts and facets in the mid and lower snowpack can still be found in isolated pockets.
