Official Expedition Narrative & Archival Record

In spring 1999, Juanito Oiarzabal led a small Basque expedition to the North Face of Annapurna I (8,091m). Annapurna was the fourteenth and final summit required for Oiarzabal to enter the elite circle of climbers who had stood atop all fourteen of Earth's 8,000-meter giants. Adhering strictly to his lifelong principle of climbing without supplemental bottled oxygen, Oiarzabal faced immense objective dangers across the notorious 'Sickle' glacier and threatening ice cliffs. Battling severe cold and unstable spring snow, Oiarzabal established Camp III at 7,200 meters. On the night of April 28, accompanied by high winds, he pushed upwards into the death zone. In the early afternoon of April 29, 1999, Oiarzabal crested the summit ridge and reached the highest point. His triumph made him the first Spaniard and only the third mountaineer in history—following Reinhold Messner and Erhard Loretan—to complete all fourteen eight-thousanders without artificial oxygen.

Annapurna I North Face (Herzog-Lachenal Route)

The North Face of Annapurna I is the historic first route ever climbed on an 8,000-meter peak, pioneered by French climbers Maurice Herzog and Louis Lachenal on June 3, 1950. Approached via the remote Miristi Khola valley, the route ascends the shattered North Annapurna Glacier, negotiates the terrifying avalanche-swept Sickle Glacier serac wall, and ascends steep snow gullies along the French Rib to gain the 8,091m summit.

Juan Eusebio Oiarzabal Urteaga was born on March 30, 1956, in Vitoria-Gasteiz, Álava, in the Basque Country of northern Spain. He began rock climbing in the Pyrenees and Picos de Europa before making his Himalayan debut in 1985 on Cho Oyu (8,188m). Possessing extraordinary physiological resilience and an outspoken, passionate temperament, Oiarzabal became the driving force behind the Basque mountaineering explosion of the 1990s. Between 1985 and 1999, Oiarzabal scaled all fourteen of the world's 8,000-meter peaks without once using supplemental bottled oxygen. On April 29, 1999, he stood on the summit of Annapurna I (8,091m), completing the 14 Eight-Thousanders. He became the first Spaniard and only the third climber in history (after Reinhold Messner and Erhard Loretan) to complete the feat without bottled oxygen. He also achieved the rare distinction of summiting the three highest mountains on Earth—Everest, K2, and Kangchenjunga—without supplemental oxygen. Never content to rest on his laurels, Oiarzabal launched his ambitious '2x14' project: becoming the first person to climb all fourteen eight-thousanders twice. By 2012, he had amassed twenty-six individual summits of 8,000-meter peaks—the all-time world record for most summits above 8,000 meters. His career was marked by incredible grit; in 2004, after surviving a catastrophic descent from K2 in which he suffered severe frostbite that necessitated the amputation of all ten toes, Oiarzabal returned to the death zone to continue climbing. He is widely decorated with Spain's Gold Medal of the Royal Order of Sports Merit.
