Vertical Run | 30ft |
Small isolated slabs released by skiers in two different turns on the same run at the north side of the pinnacle getting to the bottom of the valley, at slightly different elevations but same aspect. Both probably were D1, low vis didn't allow to see a lot but we saw them start and run. We also saw shooting cracks during the day at different elevations and aspects. The surface snow was moist up to the ridges with good cohesion and bad bonding to older snow. Crown varied from 3-6" thick.
