It actually only burried one person. the Slide was on the other side of teh first patch of trees that you see there. the bowl with all of the tracks was bombed out by the snow birds and let gow a huge avalanche also.
yeah thats one of the first things they tell you in those avalanche safety packets, that avalanches are usually not actually triggered by the first person. not that i have any real backcountry training though.
