Observer Comments

This avalanche likely released Wed, Feb 13th naturally. It looks to have pulled out several pockets of wind slab on the flank and also stepped down into older snow closer to the gut.

There are also other natural wind slabs from the past 1-2 days in the paths next to the larger one mentioned. See photos.
