offers of help. The rescuers replaced the hat, jacket and gloves Mr. Hall had discarded, anchored him to the mountain, and gave him their own oxygen, food and water. They radioed Hall's team, who had given him up for dead, and convinced them he was still alive and must be saved. Mr. Hall's team leader had already called his wife the night before to tell her that Hall was dead. The rescuers arranged for Sherpas from Mr. Hall's team to ascend and help with the rescue. For four hours, Mazur's team stayed to care for Mr. Hall. Phil Crampton coordinated the rescue from the high camp at 26,000 feet, and Kipa Sherpa was the liaison to Lincoln Hall's team at advance base camp at 21,000 feet. Extended stays at extreme altitude are risky even when planned in advance and when climbers have all the supplies they need. By using their own survival supplies to sustain Hall, going to the summit after so many hours spent helping Hall was out of the question. Staying there to care for Hall, they took a risk the weather would turn for the worse and they might even not have sufficient oxygen and food to support themselves on the way down. In abandoning their own attempt on the summit in order to save Hall's life, epitomized the noblest traditions of mountaineering. Mazur said of his team abandoning their summit attempt, "The summit is still there and we can go back. Lincoln only has one life." Several print as well as television documentaries tell the story in detail. Their actions were underscored by the death of British climber David Sharp a few days earlier, a solo climber who had been terribly sick and other mountaineers who passed by him on their way to the summit. Rick Allen rescue During the 2018 Broad Peak Expedition, Mazur and his team rescued Rick Allen, a British climber who disappeared at night near the summit and whose team mates reported him dead and descended with Rick's satellite phone. Mazur and team found Rick Allen alive and brought him down to base camp 3 days later. Community and environmental engagement Each year Mazur leads and organizes groups of volunteers to visit, bring supplies, medicines, health care and education to the Himalayas.
