Comments:
Came across a skier triggered D2 slab off the Kendall Knob Ridge dropping toward main Kendall slidepath (SS-AS-D2-R2-S N 4500). Tracks leading in and out, but did a quick beacon rule out anyway. Maybe 100' wide, 1-1.5' deep and ran around 200'. Didn't investigate the crown.

Observations

Saw another 3 naturals up near the Kendall ridgeline. 1 of which looked quite large, but it was pretty flat light when I spotted it, so hard to gauge. The other two looked like wind slabs.

Noticed a crown on E/NE aspect of Humpback ~4000' on the drive home.
