Kabru is a mountain in the Himalayas on the border of eastern Nepal and India. It is part of a ridge that extends south from Kangchenjunga and is the southernmost 7,000 metres (23,000 ft) peak in the world.

The main features of this ridge are as follows (north to south):

To the south west of Kabru south, there is a 6400 m saddle and a 6682 m summit known as Rathong. To its south east is the 6600 m Kabru Dome.

In 2004, a group of Serbian climbers unsuccessfully attempted the mountain. A series of avalanches forced the group to give up their goal.

Site of altitude records[edit]

The 7338 m summit of Kabru is the site of a mountaineering altitude record, either in 1883 or in 1905. The English barrister William Graham, the Swiss hotelier Emil Boss and the Swiss mountain guide Ulrich Kauffmann reported to have reached a point 30-40 feet below this summit, which Graham described as "little more than a pillar of ice", at 2pm on October 8, 1883. The ascent was questioned by powerful members of the Alpine Club and the Indian Survey Department, though not by their Himalayan climbing colleagues, and has been dismissed for most of the time since. Recent analysis suggests that the mountaineers may have been correct in their assertions after all.[1] If Graham, Boss and Kaufmann did climb to ~7325 m on Kabru it was a remarkable achievement for its time, breaking the existing altitude record by at least 360 m (assuming a pre-Columbian ascent of Aconcagua) and holding on to it for twenty-six years (when in 1909 an expedition led by Luigi Amedeo, Duke of the Abruzzi reached about 7500 m on Chogolisa).

If their account is dismissed, the same peak nevertheless became the site of an undisputed altitude record on 20 October 1907, when the Norwegians Carl W. Rubenson and Monrad Aas came within 50 m of climbing it. Notably, Rubenson and Aas believed that Kauffmann, Boss and Graham had reached the same point 34 years before.[1]
