Snowpack Summary
Dry, powder snow remains on shaded (northerly) slopes. While moist snow or thin crusts exist on most solar slopes at all elevations.
The mid snowpack contains several persistent weak layers including layers of surface hoar in wind-sheltered terrain and old crusts on south-facing slopes. No recent activity has occurred on these layers.
The lower snowpack includes a layer of large, weak facets and or depth hoar crystals.
