Comments
D1 Soft slab remotely triggered from ridge. Coudn't see it, as it went through the forest. But looking at a topo I'd guess it ran 150'-200' vertical. Skied south aspect from ridge with no slab or other signs of instability. Also skied lower angle lower elevation NE, and E aspects on nearby circle all with dry loose sluffage the only sign of instability.
