At the same time, Tombazi also claimed to have made some early sightings of the Yeti while climbing in the region.

[9] Mountaineering in Sikkim was abundant during the time of British India, with most climbing activity in the region taking place between 1929-1939.

[10] In the years since, the saddle Zemu Gap (5,861 m or 19,229 ft) has been rarely attempted by climbers, partly due to its remoteness and difficult approach, with wide crevasses preventing passage.

[11][6] In 2008, a British team consisting of Adrian O’Connor, Colin Knowles and Jerzy Wieczorek from attempting to reach the saddle Zemu Gap from the south was prevented by icefall and poor weather.
