Official Expedition Narrative & Archival Record

In May 2008, Navarrese mountaineer Iñaki Ochoa de Olza and Romanian partner Horia Colibășanu launched an alpine-style push up the formidable South Face of Annapurna I (8,091m) without supplemental bottled oxygen. On May 19, high at Camp IV at 7,400 meters, Ochoa suffered a severe seizure resulting from acute high-altitude cerebral edema and pulmonary complications. Colibășanu heroically refused to descend to save himself, remaining by Ochoa's side in sub-zero cold for three days to administer medication and melt snow. An unprecedented multi-national rescue effort spontaneously formed at Base Camp. Swiss alpine speed record-holder Ueli Steck and Simon Anthamatten sprinted up the avalanche-swept face with vital dexamethasone, while Denis Urubko, Don Bowie, and Russian climbers carried heavy oxygen cylinders up the lower glaciers. Steck reached Ochoa's tent at 7,400 meters on May 21, nursing him through severe storms. Despite these heroic efforts, Ochoa passed away on May 23, 2008. The rescue operation was universally hailed as one of the most selfless demonstrations of alpine brotherhood and solidarity in Himalayan history.

The South Face of Annapurna I is one of the most formidable big-wall arenas in world mountaineering, rising 3,000 vertical metres of sheer rock, ice flutings, and overhanging bands directly from the Annapurna Sanctuary. First ascended via siege tactics by Dougal Haston and Don Whillans in 1970, it was later climbed in a revolutionary, lightweight solo push by Swiss alpinist Ueli Steck in October 2013 in just 28 hours round-trip.

Iñaki Ochoa de Olza Seguín was born on May 29, 1967, in Pamplona, Navarre, Spain. Drawn to the Pyrenees in his youth, he took part in his first Himalayan expedition at age twenty-two on Kangchenjunga in 1990. Over the subsequent eighteen years, Ochoa completed more than thirty high-altitude Himalayan expeditions, summiting twelve 8,000-meter peaks—including Cho Oyu, Gasherbrum I, Gasherbrum II, Lhotse, Everest, Nanga Parbat, Broad Peak, Makalu, K2, Manaslu, Dhaulagiri, and Shishapangma—strictly without supplemental bottled oxygen. Ochoa was celebrated throughout the climbing community for his pure, honest alpine philosophy. He refused commercial fixed ropes, carried his own loads, and rejected modern commercial summit chasing. His humor, philosophical writings, and warm camaraderie made him one of the most beloved figures in Himalayan mountaineering. In May 2008, Ochoa launched a lightweight alpine attempt on the South Face of Annapurna I alongside Romanian climber Horia Colibășanu. High at Camp IV at 7,400 meters, Ochoa suffered a severe seizure, collapsing from high-altitude cerebral edema and pulmonary complications. Colibășanu refused to leave his side for days, sparking one of the most legendary international rescue operations in mountaineering history. Swiss soloist Ueli Steck and Austrian climber Simon Anthamatten sprinted up the mountain with medical supplies, while Denis Urubko, Don Bowie, and Russian climbers carried oxygen bottles up the lower flanks. Steck reached Ochoa and nursed him for two days, but despite extraordinary efforts, Ochoa passed away on May 23, 2008. In his memory, the SOS Himalaya foundation was established, building schools and hospitals for children across Nepal.
