Y.C. explosive triggered slide

"The YC Ski Patrol conducted avalanche mitigation work above another one of our roads today. The area is outside of our ski area boundary and receives no skier traffic. A 4lb explosives charge was detonated from an aerial tram and triggered a R2/D2 avalanche that ran to the ground. The crown was 2', the path width was around 100', and it ran 350 vertical feet (crossing the road) to the bottom of the runout zone. The elevation was 7280' on a NNW aspect and max slope angle of 34 degrees. Other sections of this slope were tested with explosive charges, yielding only black holes."
