Triggered a small (size 1) on a steep (50 ish) SE aspect just above TL. 20cm has of storm/wind slab on rain crust. 2 skiers caught, slid 10m, one partial (Knee height) burial. Slab was not very dense but did propagate above trigger point and 25m wide. Lots of evidence further down of similar slides, mostly on steeper terrain and same aspect all the way through tree line.
