There was a strong wind (~30 mph) from the Northwest transporting snow over the ridge and depositing it on the popular slope just off of Point Supreme in Dry Fork of AF Canyon. My first cornice kick gave me a small reaction on a South facing slope, 8" deep, 30 feet wide, and nearly 100 feet long of a medium density wind slab). Not high energy, but the cornice section that fell and triggered it was only about microwave sized.
The next one I got to and kicked broke about 10" deep, 80 feet wide, and ran out 200 feet. As that one went, it another slide that was a bit deeper and wider broke about 200 feet away towards Sunset peak. I don't know if it was sympathetic or natural and the timing was coincidental.
I called Alta Dispatch and reported them, and carried on along the ridge.
