Bulgarian Ama Dablam Attempt. This Bulgarian expedition led by Venelin Petrov had hoped to climb a new route, the northwest ridge to the west face. They were badly delayed because cargo by truck from Bulgaria failed to arrive on time and they had been on the mountain only for four days when the big October blizzard struck. Valeri Gueorguiev Peltekov and Nicolai Apostolov Proev reached 5600 meters on October 23 and then the climb was abandoned because of dangerous snow conditions.
