Avalanche on Red Lake Pk

2nd hand, reliable info:

Complex terrain, crown varied from 4" to 8" and just under rocks. Buried skier suffered head injuries and was flown to Reno - so specific observations (bed surface, etc) are limited. Even though the crown itself was shallow, debris was at least waist deep, and enough for complete burial. Start zone reported to be steeper than 35 degrees, but again not measured due to serious injuries.

11.29 edit:

Andy and I visited site for investigation. Upon approach, 3 snowboarders descended similarly complex terrain just to the climber's left of yesterday's accident, on a slightly more northern aspect. They triggered 2 very small slabs at about the same elevation, with about the same crown height as yesterday's accident, but much smaller avalanches - with no consequences. Two other travellers descended terrain ~300 meters to climbers left with no results.

2 other crowns were observed on either side of accident - both appeared to be natural triggers that may have occured just before accident.
