Avalanche Details

1st skier triggered hard slab at top of headwall on first turn, fracturing 15-20 feet above, entire width of headwall, 4 to 12 inches deep. Skier was carried and tumbled down 2/3 of slope. No injuries, not buried and no lost gear.

Before the avalanche everyone was fighting the cold weather. We had discussed a belay over the rollover and had the resources for it, but cold wind and a sick group member pushed our decision the faster way.
