Mt. Everest, solo attempt. In the spring of 1952 a Dane, Klaus Bekker Larsen, with four Sherpas, traveled from Darjeeling to Namche Bazar and climbed to the Lobujya Khola between Nuptse and the Lho La. After they were forced back from there, they crossed to the Rongbuk Monastery and followed the old English route on Mt. Everest to within 300 feet of the North Col. Lack of equipment prevented further progress, although the weather continued favorable.
