An Austrian has become the first woman to reach all 14 Himalayan summits above 8,000m (26,000 ft) without using bottled oxygen.
Gerlinde Kaltenbrunner, 40, set the record after conquering the treacherous K2.
"She is over the moon," quoted her husband as saying on Mrs Kaltenbrunner's website.
Mrs Kaltenbrunner, a nurse, is only the third woman to reach all 14 highest summits, but the first two climbers used supplemental oxygen.
"SUMMIT!!! At 6:18pm local time, Gerlinde reached the summit of K2," her husband Ralf Dujmovits said on the climber's website on Tuesday (23 August, 2011).
The Austrian was accompanied by three other climbers to the top of the 8,611m mountain - the world's second tallest after Mount Everest in Nepal.
"Gerlinde is over the moon and can't believe how lucky they were to reach the summit together in this fantastic weather, despite the difficult conditions during the ascent," Mr Dujmovits added.
