Biographical Record & Archival Chronicle
Born in the Makalu region of Sankhuwasabha, Sona Sherpa rose through the ranks of Nepal's premier mountaineering agency, Seven Summit Treks, to become one of their most dependable high-altitude guides. Known for his modesty, endurance, and extraordinary strength in severe cold, Sona logged ascents of Everest, Manaslu, and Annapurna before taking on the winter challenge of K2.
In the winter of 2020β2021, when multiple international teams converged on K2, Sona Sherpa provided essential high-camp logistics and route maintenance.

Associated Summits (1)
K2
K2, at 8,611 meters (28,251 ft), is the second-highest mountain on Earth and widely regarded as the most technically demanding and lethal 8,000-meter peak. Located in the heart of the Karakoram on the border between Pakistan and China, K2 is characterized by sheer relief, severe weather anomalies, and persistent objective hazards including the notorious Bottleneck couloir.
Pioneered & Associated Routes (3)

Abruzzi Spur (Southeast Ridge)
The Abruzzi Spur is the most famous and frequently climbed route on K2, tracing the mountain's steep southeast ridge from the Godwin-Austen Glacier to the summit. First explored in 1909 by Prince Luigi Amedeo, Duke of the Abruzzi, it was successfully climbed to the summit in 1954 by an Italian team. The route requires extreme physical endurance and high-grade technical climbing on rock, ice, and mixed terrain through legendary cruxes like House's Chimney, the Black Pyramid, and the Bottleneck couloir.

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.
