Weather
Partly Cloudy, felt like January, light NW winds with moderate gusts.
Snowpack
We traveled primarily on S and SE aspects near and above treeline. 4-5 inches of low-density, faceting snow is resting on crusts from earlier in November. As we gained elevation towards the ridge a thin wind crust was present on the surface. Closer to the ridge the wind crust grew to an obviously thicker slab up to 18? thick. Northerly winds caused off-and-on snow transport onto southerly aspects.
Avalanche
Observed a D1.5 Wind Slab that likely ran yesterday or overnight. Ski-triggered another Wind Slab from ridgeline adjacent to the natural. This one propagated a bit wider and reached D2 size entraining the softer snow in wind-protected terrain as it ran around 600 ft. Debris was up to 5 ft deep.
