I was a bit surprised to run into this broad fresh wind slab, but it was on a heavily drifted slope... Southwest winds found plenty of soft snow to transport, and the south side of the ridge was scoured down to rocks. The hard slab avalanche was 1 to 3 feet and 400 to 500 feet wide and it stacked up a considerable pile of debris in the trees below. Most of the avalanche stopped after only running 50 vertical feet or so, but parts ran quite a ways further through the trees.
