Avalanches: Triggered 2 small slabs both running within the new snow on drifted features near and below tree line. Crowns averaged 6-10″.

Weather: Overcast, S1-S2 snow showers with 2′ accumulation during the day. Cold with moderate NW winds in large open areas below tree line and all near tree line locations.

Snowpack: HST 14″ at 3:30 pm.  Measured 12″ with .8″ SWE at 10:00. Overnight snowfall was low density at around 6%. Density increased slightly through the day but remained quite enjoyable.

Open slopes near tree line in this terrain were getting cross-loaded by moderate WNW winds throughout the day.
