Observer Comments

We were a party of five + 2 K9, on the second lap. The last skinner heading up heard a whooph and a 3' deep 150' long slide occurred. Skier moved 10'staying atop and stopped. Skier watched dog try to get out and then dog was swallowed by the avalanche. Dog self rescued as the slide stopped. Slide was in the trees with numerous anchors. Using cell phone app and personal experience slope was estimated at 20 degrees at most.
