the Himalayas. The successful Dunagiri trip by the ANUMC forged the Hall and Macartney-Snape partnership, setting the stage for their Himalayan mountaineering careers including their 1984 Mount Everest expedition. After Dunagiri, Hall participated in and led numerous climbing adventures around the world, including many first ascents by Australian climbers. Amongst these were two expeditions to climb Mount Everest in Nepal (including the first Australian ascent in 1984); the first ascent of Mount Minto in the Admiralty Mountains of Antarctica (1998); and ascents of other notable peaks including Annapurna II (7963m) in Nepal, Makalu (8481m) on the China-Nepal border, and Carstensz Pyramid in Irian Jaya, Indonesia. Rescue on Everest Lincoln Hall narrowly survived after his ascent of Mount Everest in 2006. He was left for dead at an altitude of 8700m while descending from the summit on 25 May 2006. He had fallen ill from a form of altitude sickness, probably cerebral edema, that caused him to hallucinate and become confused. According to reports, Hall's Sherpa guides attempted to rescue him for hours. However, as night began to fall their oxygen supplies diminished and snow blindness set in. Expedition leader Alexander Abramov eventually ordered the guides to leave the apparently dead Hall on the mountain and return to camp. A statement was later released announcing his death to his friends and family. However, the next morning, 12 hours later, Hall was found still alive by a team making a summit attempt. The team consisted of team leader Daniel Mazur (U.S.), Andrew Brash (Canada), Myles Osborne (UK), and Jangbu Sherpa (Nepal). Osborne described the scene just below the Second Step: "Sitting to our left, about two feet from a 10,000 foot drop, was a man. Not dead, not sleeping, but sitting cross legged, in the process of changing his shirt. He had his down suit unzipped to the waist, his arms out of the sleeves, was wearing no hat, no gloves, no sunglasses, had no oxygen mask, regulator, ice axe, oxygen, no sleeping bag, no mattress, no food nor water bottle. 'I imagine you're surprised to see me here', he said. Now, this was a moment of total disbelief to us all. Here was a gentleman, apparently lucid, who had spent the night without oxygen at 8600m, without proper equipment and barely clothed. And ALIVE." A rescue effort that mountain observers described as "unprecedented in scale" then swung into action. Mazur and
