This avalanche was triggered with explosives by the Big Sky Ski Patrol. The snow structure at the crown was very similar to the snow Mark found on a slope in Beehive Basin (his snowpit). Mark's stability tests showed stability, but he did not believe it given the poor structure. Be on the lookout for false stable test results. Photo: BSSP
