October 01, 2009

On September 24, 2009, extreme mountaineer and solo climber Ueli Steck reached the summit of the 8362-meter peak Makalu via the normal route. Makalu is the fifth highest mountain in the world and lies to the east of Mount Everest on the border between Nepal and China. Together with Robert Bösch, he left camp 3 at 7350 meters above sea level at 3 a.m. on September 24. The route to the summit was covered in snow. At an altitude of approx 7900 meters, Robert Bösch turned back. Ueli Steck reached the summit at around 3 p.m. He returned to camp 3 at an altitude of 7350 meters the same day. You can read the full story of this ascent on Ueli Steck’s homepage. Since last year, Katadyn has been supporting Ueli Steck with Katadyn water treatment products, Trek’n Eat expedition food as well as outdoor stoves and stove accessories from Optimus. During his ascent of Makalu, Ueli Steck had Peronin on him. The liquid food, enriched with vitamins and minerals, has been used successfully by high-altitude mountaineers and other extreme athletes for many years.
