At the end a wonderful afternoon side country tour, I was stomping on wind affected snow on the way back up Goulie with no significant reactivity. Then out of the corner of my eye I spotted some blocks of snow mid slope on the north aspect. The terrain felt safe enough to side hill over to it and sure enough, an old D1 avalanche that likely went at the tail end of the last storm. It seemed to be triggered by a tree bomb and propagated approximately 150' taking only the top 7 or 8 inches of storm snow with it.
