Ang Dorje has led many successful expeditions on Everest, frequently as climbing sirdar for Adventure Consultants, the guiding service founded by Rob Hall. During the disastrous 1996 expedition on Everest, he and Lhakpa Tshering Sherpa attempted to rescue Hall and others, in the deadly storm conditions that ultimately killed 8 climbers. They ascended 900 vertical meters to just below Everest's South Summit, only to be halted by impenetrable storm conditions just 100 meters from Hall. They waited 45 minutes before being forced back by the storm. Ang Dorje later commented on the incident saying, It was very sad. Very difficult. The rescue efforts were recounted by Jon Krakauer in his account of the disaster, Into Thin Air.
