More information or comments about the avalanche:
We observed wide, old (almost filled in) crowns. These were all on east and north aspects along the base of cliffs in wind loaded terrain. Debris piles were covered. I would assume they were large enough to bury or injure a human given the terrain and distance they would have ran.
