me and my partner witnessed/experienced a D2 R3 full course slab avalanche in the Ripper Chute on the Dana Plateau on March 23 at approximatley 11:30am. Skies were overcast and temps below freezing. One snow traveler was able to self arrest while the lower climber 10' below was swept the entire course of the couloir. After sustaining minor injuries it was assesed that the climbers splitboard was buried in the debris and the snow taveler/climber walked/glissaded on a shovel out to the trailhead. The said snowtraveler will be very interested in finding the said buried spitboard. Or it may be hung up on rocks higher in the Couloir...
