Biographical Record & Archival Chronicle

Nirmal 'Nimsdai' Purja was born on July 25, 1983, in Dana, a small village in the Myagdi District of western Nepal. Raised in Chitwan in the southern lowlands, he dreamed from childhood of military service. In 2003, at age nineteen, he joined the legendary British Brigade of Gurkhas, serving with distinction before becoming, in 2009, the first Gurkha to pass the grueling selection for the UK Special Forces' elite Special Boat Service (SBS). Across nearly a decade of classified combat operations as a cold-weather warfare specialist, Purja honed the extreme mental grit, physiological stamina, and high-stakes operational planning that would subsequently transform high-altitude mountaineering.

Purja's climbing journey began during military leave in 2012 when, with zero prior mountaineering experience, he trekked to Everest Base Camp and summited Lobuche East (6,119m). In 2014, he achieved his first 8,000-meter summit on Dhaulagiri I after just fifteen days of acclimatization. In 2016 and 2017, he led Gurkha expeditions to Mount Everest, summiting twice and pioneering fast-rotation tactics. Recognising his extraordinary high-altitude physiology, Queen Elizabeth II appointed Purja a Member of the Most Excellent Order of the British Empire (MBE) in 2018 for outstanding achievements in extreme high-altitude mountaineering. Months later, he resigned from the Special Forces just years short of a guaranteed lifetime military pension to pursue a lifelong dream that seasoned alpine authorities deemed impossible.

In 2019, Purja launched 'Project Possible 14/7'—a mission to summit all fourteen of the world's 8,000-meter 'death zone' peaks in just seven months, shattering the previous world record of seven years, ten months, and six days set by Kim Chang-ho. Starting on April 23 on the avalanche-prone north face of Annapurna I, Purja conquered Nepal's giants in rapid succession: Dhaulagiri, Kangchenjunga, Mount Everest, Lhotse, and Makalu. On Everest, Lhotse, and Makalu, he established a staggering record by summiting all three peaks in only 48 hours. Beyond speed, Purja gained global admiration for stopping his own climbs to lead life-saving high-altitude rescues, including the helicopter rescue of Dr. Chin Kin Wah on Annapurna and assisting stranded climbers on Kangchenjunga.

Phase 2 of Project Possible swept through Pakistan's Karakoram in July 2019. In just twenty-three days, Purja summited Nanga Parbat, Gasherbrum I, Gasherbrum II, K2, and Broad Peak. On K2, when dozens of international teams were paralyzed by deep snow and severe avalanche danger in the Bottleneck, Purja and his team of Nepali climbers took charge of route-fixing, broke trail through the drifts, and spearheaded the successful team summit push. Moving to Tibet for Phase 3, he claimed Cho Oyu on September 23 and Manaslu on September 27. When China initially withheld permits for Shishapangma, international diplomatic appeals facilitated by the Nepali government led to special clearance. On October 29, 2019, Purja stood on Shishapangma's summit, completing all fourteen 8,000ers in just 189 days (6 months and 6 days).

Fifteen months later, on January 16, 2021, Purja achieved high-altitude immortality by co-leading the historic first winter ascent of K2 (8,611m)—the last remaining 8,000-meter peak unclimbed in winter. In arctic temperatures of −65 °C, two Nepali teams unified their efforts. Purja chose to push for the summit entirely without supplemental oxygen, a feat of immense physiological defiance given his lack of high-camp acclimatization. Halting ten meters below the summit, all ten Nepali climbers linked arms, sang Nepal's national anthem, and stepped onto the summit together at 4:58 PM. Purja's career has redefined high-altitude mountaineering, shattered Western-centric historical paradigms, and brought rightful global recognition to Nepali and Sherpa climbers as supreme high-altitude masters.

Mount Everest Southwest Face (Bonington Route)

The Southwest Face of Mount Everest (8,848.86m) rises 2,300 vertical meters from the Western Cwm to the summit, presenting one of the largest and most forbidding rock and ice faces in the world. Dominated by the vertical 300-meter 'Rock Band' at 8,200–8,500 meters, the face repelled six international attempts between 1969 and 1974. In autumn 1975, a legendary British expedition led by Chris Bonington breached the face when Paul Braithwaite and Nick Estcourt unlocked the key ramp through the Rock Band. On September 24, 1975, Doug Scott and Dougal Haston climbed to the South Summit and pushed on to the main summit, becoming the first Britons to conquer Everest. Trapped by nightfall during their descent, they survived an epic open bivouac at 8,760 meters without oxygen, sleeping bags, or frostbite.

The Complete West Ridge of Mount Everest is one of the most formidable and sustained technical routes on the mountain. Pioneered in spring 1979 by an elite Yugoslav expedition led by Tone Škarja, the route tackles the integral knife-edge crest directly from the Lho La col (6,026m) all the way to the 8,848.86m summit. Unlike the 1963 American West Ridge route which diverted into the Hornbein Couloir from the North Face, the Yugoslav line stayed strictly along the razor-edge crest of the West Ridge, surmounting technical rock buttresses up to Grade V+ at extreme altitude before traversing around the Yellow Band. On May 13, 1979, Andrej Štremfelj and Nejc Zaplotnik achieved the first ascent of the complete ridge, followed two days later by Stane Belak, Marjan Manfreda, and Ang Phu Sherpa in one of the greatest feats in Himalayan history.

Northwest Face & Japanese Couloir (Normal Route)

The Northwest Face via the Japanese Couloir is the standard and most frequently climbed line on Gasherbrum I (8,068m / Hidden Peak). Starting from the South Gasherbrum Glacier, climbers traverse the shared lower icefall into the Gasherbrum Cwm, then branch southward toward the forbidding northwest wall. The technical centerpiece is the Japanese Couloir—a sustained 50 to 60-degree gully of hard blue ice and shattered rock leading to the high col and summit slopes. First ascended in 1958 by Americans Pete Schoening and Andy Kauffman via the South Ridge, the Japanese Couloir line became the modern benchmark, climbed rapidly in 1992 by Nazir Sabir, Rajab Shah, and Mehrban Shah.

Southwest Ridge (Normal Route)

The Southwest Ridge is the standard and historically celebrated route on Gasherbrum II (8,035m). Starting from the South Gasherbrum Glacier, climbers navigate the heavily crevassed lower icefall into the Gasherbrum Cwm before tackling the technical crux of the route: the steep mixed snow and ice crest known as the Banana Ridge. Above Camp III, the route traverses expansive snow basins into the Death Zone, making a final push up a delicate diagonal couloir to the summit. First climbed in 1956 by an Austrian team, and completed in rapid alpine style in 1982 by Reinhold Messner, Nazir Sabir, and Sher Khan.

K2 South Face (The Polish Line)

The Polish Line on the South Face of K2 (8,611m) is widely regarded as one of the most perilous and audacious routes ever climbed in high-altitude mountaineering history. Tackling the direct 3,200-meter wall between the Abruzzi Spur and the Magic Line (South-Southwest Pillar), the route ascends through a chaotic labyrinth of hanging seracs, avalanche funnels, and vertical rock bands. Pioneered in alpine style over five harrowing days in July 1986 by Jerzy Kukuczka and Tadeusz Piotrowski without supplemental oxygen, Reinhold Messner famously dubbed it 'suicidal'. Kukuczka and Piotrowski reached the summit on July 8, but tragedy struck during their desperate descent via the Abruzzi Spur when Piotrowski lost both crampons and plunged to his death. To this day, the Polish Line remains unrepeated.

West Ridge (Japanese Route)

The West Ridge of K2 is one of the most formidable and sustained technical lines in high-altitude mountaineering. Pioneered in August 1981 by a joint Japanese-Pakistani expedition, it ascends directly from the Savoia Glacier along the exposed western crest before negotiating the severe Southwest Face directly into the Death Zone. Demanding immense commitment, it was first completed by Pakistani mountaineer Nazir Sabir and Japanese climber Eiho Ohtani after an epic bivouac near 8,500 meters.
