Quick report
This was a larger/deeper slab than we expected today and observing this avalanche caused us to step it back - we closed any large open slopes such as Wenatchee Bowl directly on the other side of the ridge from this slide.
Avalanche
5600 ft D2 SE aspect natural slab with ~40cm crown ~80 feet wide - appeared to be triggered by a smaller D1 storm slab with ~15cm crown higher on the ridge.
