New Zealand AC Himalayan 1954
This expedition of mostly New Zealand climbers set out to explore the Barun glacier to the east of Everest. As well as a trigonometric survey, the expedition also carried out a reconnaisance of Makalu (climbing to 7000m before retreating due to the collapse of Edmund Hillary) and made the first ascents of more than 20 peaks, including Baruntse (7162m).
