Skier remote trigger on NW aspect in West bowl of Willow. We were standing on a 31 degree slope but the slide ran on 38 degree slope about 200 feet from skier. Crown 1.5 feet on buried SH, 60 feet wide, ran approx 400 feet into trees

Amazing amount of collapsing on south facing aspects all day. We found multiple crusts with facets between, beneath approx 10 inches of new snow. We probably had 15 collapses all day on low angle slopes but saw no cracking associated with this collapsing

New snow is quite dense
