My partner and I triggered this slide from the ridgetop. We heard a huge collapse and watched cracks propagate alonfg the ridge before avalanching the cornices and slope below. The slide propagated up and down the ridge about 1,000 feet. The crown was 3-5 feet deep and was a hard slab that pulled out trees. It was a north to northeast aspect at 9,500 feet. It ran about 600 feet vertical . Check out the video of the aftermath. Photo: GNFAC
