Moderate to heavy snow all day. Temperatures got warmer throughout the day but it stayed snow down to the trailhead at Johnson Pass (600 ft ish). Winds were light to moderate at treeline and transporting snow above treeline. Visibility was obscured.
New snow. About 10" over the Monday/Tuesday crust at trailhead. Gradually increasing to 12-14" at treeline.
We dug a pit at treeline around 2000' on a west aspect. No propagation in ECT, but we got an ECTN 9 on the new snow old snow interface (which is the interface that avalanched in our way down). The new year's crust was 90cm deep and total snowpack was 270cm.
