Avalanche report
- Comment
- First skier triggered wind/storm slab traversing to skiers right path from skiers left path after just skiing down the gut of the left path with no issues. Propagated behind skier to sympathetically release adjacent slope. Approximately 50M wide, 15-30 deep, slow moving. Triggered near rocks and a thin spot. Eventually entrained enough material to potentially cause a bad time with small trees below. No involvement, skier easily made it to flank. Bed surface previously sun and wind affected, poor bonding surface. Ran approximately 200M, small powder cloud.
