Avalanche Summary
A few size 1 wind slabs and wet loose avalanche activity were reported on Saturday. Read about them in this MIN
Several small explosive-triggered wind slabs and size 1 to 1.5 wet loose from steep solars on Friday.
Snowpack Summary
Recent accumulated snow is settling on north-facing slopes and is moist on steep south-facing slopes, which overlies a crust on all aspects and elevations that is more robust on solar-facing slopes.
A widespread crust with facets above is down 60 to 110 cm. This layer is unlikely to human trigger in areas where a thick crust above the weak layer is present.
