Weather

Snowed on and off throughout the day. Mostly S1 but periods of S2. Winds were light out of the SW near and below treeline.

Snowpack

~4" of new snow feel in the past 24 hours on ~10" on new snow from the past week. Snowpack tests showed failures on the old snow surface and a well developed weak-layer of snow near the ground. The snowpack was falling in the middle of the pack on the old snow surface prior to last week. A thin crust was observed buried on sunny slopes. No signs of insatiability were observed today, but this is a heavily used area.
