See above. Near miss. An ice climber was killed in Provo Canyon on the Fang Jan 25 1997 by a similar event.

A significant amount of snow fell on us as we were ice climbing in Hogum Right. We were on the last pitch and briefly saw a large wall of snow come over the overhanging cliff above us. The climber leading was hot continuously for about 10-15 seconds but was able to prevent taking a lead fall. The belayer was partially buried. Primary concern was if it would have knocked the leader off while climbing or hit us during one of the unroped segments that still had enough exposure that getting knocked down would have resulted in injury.
