[1][2] Prior to starting Adventure Consultants, Hall and Ball climbed the Seven Summits in a seven-month time frame.

[3] Rob Hall's friend and climbing partner Gary Ball died in his arms on 8,167m Dhaulagiri in October 1993.

[1] The disaster became very well known, with ten million people reading about it in the book Into Thin Air, written by Jon Krakauer (who was actually on the expedition) and hearing it referenced in a highly acclaimed IMAX film, shot during the same disastrous climbing season, although the filmmakers summitted later in the season.

[8] (see also List of people who died climbing Mount Everest) Despite the disaster in the spring 1996 and the death of Rob Hall, the company already had clients for a Cho Oyu expedition.

[11] One route is through jungle, although some have tried to go through a nearby mine only to be taken prisoner, caged in a metal box, and escaping only after paying a bribe.

[12] Adventure Consultants was contacted for information about hurt climbers during the 2015 Mount Everest avalanche, and they reported that people had been evacuated, including one Sherpa who was sent to Kathmandu Medical College.
