the summit, while undergoing physical and mental tests to record the effects of altitude on humans. In July 2003, Viesturs and a Kazakh team, headed by Denis Urubko, were instrumental in the rescue of French climber Jean-Christophe Lafaille from Broad Peak. Lafaille had developed high-altitude pulmonary edema and was unable to complete his descent. They coordinated a rescue attempt in the dark, and were able to get Lafaille safely off the mountain and helicoptered out for medical help. In 2005, Viesturs became the first American, and 12th climber in history, to summit all 14 mountains over 8,000 meters (collectively known as the eight-thousanders). He is the 5th climber in history to do it without the use of supplemental oxygen. Viesturs has summitted Mount Everest seven times. Research published in 2022 estimated that Viesturs was one of only three climbers in history to have stood on the "true" geographical summit of all the eight-thousanders and that Viesturs was the first to do so. Viesturs' more recent climbs have included Broad Peak (the world's 12th highest mountain) and Nanga Parbat (the world's ninth highest mountain) in 2003, Annapurna (the world's 10th highest mountain) in 2005, and Mount Everest (for the seventh time) in 2009. On July 8, 2009 he led an expedition to Mount Rainier as part of the United Way Climb for the Community effort. UCLA coach Jim Mora, Seahawks CEO Tod Leiweke, and NFL commissioner Roger Goodell took part in this charitable enterprise, summiting the 14,410 ft peak. Viesturs led an expedition to Antarctica, in January 2011, to climb its highest peak, Vinson Massif. In May 2021, he summitted Mount Rainier for the 216th time. Viesturs now acts as a guide for RMI Expeditions. Other work Viesturs was a cinematographer for the film Trio for One (2003), which told the story of French alpinist Jean-Christophe Lafaille's mission to climb Dhaulagiri, Nanga Parbat, and Broad Peak in a period of two months. He acts as a design consultant for manufacturers of outdoor equipment, and is a representative of his adopted hometown's football team, the Seattle Seahawks. He is a member of the board of directors for Big City Mountaineers, an urban youth organization that offers wilderness experiences. Viesturs has also found a niche as a corporate motivational speaker. Awards Viesturs is a recipient of the David A. Sowles Memorial Award (1992) from the American Alpine Club. He is also the recipient
