Boukreev became widely known as the lead climbing guide for the Mountain Madness expedition headed by Scott Fischer in May 1996. The expedition was one of several attempting to summit Everest on the same day (May 10). Soon after summiting on May 10 a disastrous blizzard struck, stranding many climbers above the South Col overnight, and by May 11, eight climbers from three different expeditions had perished. Boukreev rescued three climbers stranded in the disaster above 8000 m, and all six of the climbing clients on the Mountain Madness expedition survived the ordeal.
